I guess I'm COAST fire'ing. I think I have enough and this job is just icing on the cake.
But, I'm not retiring early unfortunately. I could retire now if I wanted to though. Just too much uncertainties with the market at the moment.
I feel like coast FIRE implies a high level of optimism: "this will grow to enough by the time I turn 65, I just need to earn enough to support myself." And SWAMI implies a level of enthusiasm about one's work. Then there are those who are basically FI here and now, but don't fully trust the math or the expected spending, and so choose to cover expenses, but aren't going to be too worried if they can't from year to year...we have chosen this middle ground that best fits the term coast FIRE, but doesn't quite share in it's optimism.
It's all pretty arbitrary.
I consider anything to be CoastFI if you continue to work because you aren't totally comfortable not having income anymore. Whether that is because you haven't hit your arbitrary FI target or because you have hit it but have decided to move the goal posts for whatever reason. Regardless, you choose to keep *earning*.
If someone is a SWAMI, they're just someone who is satisfied working. They might be coasting, they might just be working and donating every penny they earn, the point is they enjoy the work. You choose to keep *working*
Choosing to keep earning and choosing to keep working are related concepts, but not equivalent.
I consider myself to be Coasting until a point that I just don't care about warning anymore. At that point, I won't stop working, just might convert all of my work energy to non-profit work, or donate all of my additional income.
What you have described sounds like coasting to me. You have saved up a bunch of money, but not enough to feel safe enough to stop earning, so you're going to keep earning to a degree that allows your savings to grow to where you will be comfortable.
Since your FI number was made up in the first place, it's not a real target, hitting it doesn't actually mean anything. It's what you thought would make you feel secure enough, but it isn't, so you are working towards that target instead.
No different from someone who works towards their savings goal and finds an amount that they're comfortable with, whether that's more or less or exactly what their initial estimate from years ago was.
That was just an estimate, not a prediction.
But even then, the concept of feeling "safe" is completely relative to how safe the person feels continuing to work. So even that isn't a number. It's the relative security provided by more money compared to the relative security provided by not working.
If you like your job, there's little risk in working. If you hate your job and it's destroying your physical well being (see the PT thread, the burnout threads, etc), then the risk of the work can easily outweigh the risk of more wealth, and can therefore move the goalposts down instead of up.
So coasting isn't about optimism, it's just the balance of factors. The person wants to continue growing their 'stache, is okay with continuing to work to do so, but doesn't want to work at their max capacity anymore.
Whether that's motivated by optimism, pessimism, or whatever doesn't matter. It's all about the balance of risks and benefits of both money and work.
