Hi I made this account just to post on this thread as I have been Work From Home (WFH) for three years.
I would like to address the fears as I shared them for a while too, I come from a sales background and the idea of shifting into WFH IT work was a big hurdle, I just love the people interaction, but I like making more money too.
becoming bored - Easily my number one concern as well. But in my time I discovered MMM, listened and read many books, played the occasional videogame, and my daughter kept me plenty busy.
Time will always be what he makes of it, but zero commute, not rushing meals, little things like that really add up
lonely and feeling disconnected - Conference calls will take care of that, but even then if you are already home I cannot see this being a huge deal. It is important to have the space be "work space" but I always pop out for a quick chat with the wife, maybe we even take a lunch (she is a stay at home mom, kid number two on the way)
not being able to "advance" - I am in IT so I cannot comment on this too much apart from saying I have gotten consistent raises.
So to wit: I love it. I get to cook breakfast for my family everyday, I get to read up on anything I want with no boss looking over my shoulder. And the times it is rough, say the odd 12 hour day, I am a few steps from my bed...and my beer.
I would suspect the MMM readers to imagine the financial benefit and they are not wrong, it is amazing. No morning coffees, no fast food lunch, no commute. (Not that we would anyway right? But still zero temptation is always a bonus) I honestly cannot imagine working any other way. Also, and this is just a random idea, if his WFH life frees up enough time he can help with your online business maybe?
So I say do it, love it, and move! I cannot wait to get out of my state and my job is the way it will happen. Best of luck no matter how it plays out for you.
