Most of my 20s really sucked. In my early 20s out of highschool, I had one job for 8 months then we moved and I didn't work for another 5 years because I had zero motivation and would be bullied into stuff by family, especially my dad. I eventually was forced to attend community college which was fine because I thought "this'll waste several years to get them off my back" but not really, was pestered to get a job to help pay bills even though I'm full time in college (lived with my mom and then sister + her family at time) although my dad was on my side about not working but didn't really matter.

Eventually, I messed up financial aid and really was hating CC due to lack of classes in network security. Decided to switch to a university and switched majors so basically had to start over from scratch for most part. Still never thought I'd succeed but I graduated nearly a year ago, started a pretty solid job 2 days after graduating and I love everything about it.

Inbetween going to college, I eventually had to work to support my mom as my sister and co moved out during that time, and she doesn't work. I worked a job for 1.5 years that I absolutely HATED. The whole building was nothing but backstabbing assholes to the point I was considering to end it or do something to my horrible boss (it was at that point I was detailing a daily log to sue my employer), but my friend got me a job at a different place and I just stopped showing up. I was at this new job for 4 years (started uni basically same time I started here) and the job was much better, but deteriorated over the years due to my first boss leaving and while I got along with everyone, I increasingly disliked it due to getting close to graduating.

So now I'm not completely, 100% happy but I'm very content with my life. I do not have everything still (GF, move out, etc) but I have an excellent job I love and no longer think I'm a failure at whatever I do. I've always been a late bloomer.
