That's what I'm aiming for. Full-on retirement seems boring.
I'm living the dream.
I was pushed out of the workforce, five years ago (Laid off, then no one would talk to an "old").
It was scary and infuriating, but, I have since found it to be the best thing that ever happened to me. I'm very fortunate, in having the means to live (fairly humbly), and not need to work.
I love writing code, though, so that's what I do; all day, every day. I found some nonprofit stuff that engages me, and I give them a level of code that they could only dream of.
I’m in my mid-20s.
Your mindset changes as you increase your years. Don't get me wrong, I love what I do. I just would rather be sitting on a bucket with a pole in the water.
Quite a few people, particularly in the trades, don't get to choose when they retire -- their health dictates it.
Plan to retire, start saving now. Even if you choose to keep working in old age, having a lot of money saved up is a nice thing to have.
