I've very nearly completed the journey (April 2015 quit date) and, looking back over the last 11 years or so, yes, I've gone through many of the things you've mentioned.
- When things aren't going well at work, I tend to deal with it by telling myself that hey, I'll be done with this in a few years and 'future me' will be happy that I've gutted it out. There have been a few periods where I focused too much on 'future me' and too little on 'current me.'
- I went through a phase 6 years ago where I checked accounts too much. I had to notice the behavior and correct it in order to put a stop to it. I set goals for myself (e.g. I will NOT check Vanguard this month -- there's no point!) and forced myself to comply. It's no different than weaning yourself off of any other compulsive behavior.
- Charitable giving went down for several years until I hit the 300K liquid assets mark (an arbitrarily defined personal goalpost, to be sure.) After that I settled on an annual giving number that worked for me and I've been hitting it ever since. I've since built this donation amount into my FIRE number.
- I also at times took cost cutting too far. Eventually I realized that it meant that my yearly spending targets were lower than they should be for me and I therefore raised my FIRE number accordingly. If you are feeling squeezed, maybe you should re-evaluate things?
It might be helpful to remind yourself that this is not a competition. You don't get a prize by hitting FI a year earlier than your initial target. Your accumulation-phase life must be a life worth living, something you feel happy and satisfied with. If you are failing on certain goals (e.g. charitable giving, or a social agenda that might cost a bit) I would urge you to re-evaluate and loosen things up in specific areas that give you bang-for-the-buck. You are alive RIGHT NOW. Enjoy it - don't completely defer your life.
A few negatives you haven't mentioned:
- Being overly critical of others who don't share the same values or path.
Example: A friend talks about buying a 5K guitar (to add to his collection of already-awesome guitars). In the past, my instinct would be to kick him in the groin and tell him THAT's why he's never going to retire. Now I just ask him about the guitar -- what makes it special? Why does he want it? Will he play Back in Black at volume 11 for me if he gets it?
I've worked hard to calm these thoughts down and not worry about finances when I'm spending time with others. Acceptance of our differences is a big part of the human experience. If you hang around the forums too much you might start to feel like it's "totally normal and OK" for you to look down on other people for their own spending choices. It's not, IMO.
- Noticing, perhaps first and foremost, the spending choices of people. This is sort of a limiting view of the world.
Example: You're in the checkout aisle of the grocery store. A couple in front of you has a carriage packed with expensive stuff that isn't even healthy: prepared meals from the frozen food section, chips and dip, fancy-pants icecream pints, lots of items that aren't bought in bulk. During your 5 minute wait for checkout service, you might just be thinking: Oh my god, these people are morons! Their monthly grocery bill must be 1K+. And you might do this every single time you go to a store. If you're always thinking about financial habits,and practically nothing else, you're missing out on lots of other things to pay attention to, like the color of the tiles on the floor or the adorable kid hopping up and down in the line next to you or the surprisingly upbeat cashier who is making eye contact with customers and chirping friendly comments to customers despite getting paid almost nothing.
Being on the FIRE path is supposed to enable a better life. It's supposed to "free" you to do and think about what you want.
If instead, all you think about is money, you're entering a different kind of slavery, one that involves a prison, and your mind. Not good.
It takes time and awareness to adjust your thought patterns. I have personally worked hard to maintain friendships with people who don't give a crap about my financial choices and life. This has occasionally meant spending money to do things with them that I wouldn't naturally do. And I have come to value the fact that they take me out of my comfort zone from time to time, even if it does mean going out to eat more than I would like, or maybe ordering that dessert to split with them. Or registering for a road race to run with a few friends even though running is a completely free activity and I shouldn't have to pay for it. We all have things we spend money on that make us happy. I've found that social events are it for me.
So what if my FIRE number went up in the process? Eventually I came to grips with the fact that I wanted both -- a so-called fairly normal social life as well as freedom from work.
Incidentally, this attitude has also made the work grind easier to bear for me. Forcing myself to construct a life that I'm *currently* happy with -- even though I'm continuing to report to the office -- has resulted in many shifts in my work-style that have made the days more bearable and sometimes even fun. I push back on stupid projects and dates. I kill time by shooting the breeze with co-workers more. I don't get all that stressed when things don't go well. I now accept work for what it is (mostly, a monumental waste of time) and I've thus adapted myself to it instead of putting up a continual fight.
Right now, for example, I'm posting on MMM instead of working on projects that I know need my attention. I'll get to them... eventually. :)
One more comment on the work thing.
My personal observation is that FU money makes work easier. "Hey, I can quit anytime and live for a while. Great. I feel much less anxious about everything now."
But FI money makes work harder. "What the hell am I continuing to work for? Why am I still hanging around here?"
The negative here is that if you don't really love your job, it becomes very difficult to stay once you're officially FI. Your logical mind will be urging you to move on to the next phase of your life.
