I want to reduce my weekly work hours by 4 to 8 hours a week because I like what I do but I fucking hate being gone 45-50 hours a week doing it. I would ideally work part time but I don't know how to make ends meet at this time if I do that.
Surely others have achieved this. /biz/, how can I cut my hours at work and make up for the several thousands of dollars a year I'll lose (depending on how many hours I cut) doing so?
I really hate working so much and the prospect of having to do it for 25+ more years before I can retire only to be diagnosed with congestive heart failure and die.
I also want to start contributing to a Roth IRA. Good or bad idea?
Thanks, /biz/.
