I still feel like i'm waiting on my life to "start".
I turn on the TV, see a high school party. Think about how maybe some day I'll go to cool older kid parties. Realize i'm 21 and 5 years older than anyone in that show.
I hear from my brother he's having some problems with a friend. Maybe someday i'll have a friend close enough to fight with. Waitaminute, if that didn't happen back in school, why should it happen now?
And of course the usual no gf ever nonsense.
I feel this way about many things. The only grown up thing I do is my job, which I actually think I do well, and the chores that come with living alone, which again I think i'm adept at. In other areas of life, I feel like a child. When my father was my age, he was in a fraternity (where he met people he still knew while I was growing up), dating my mother, and having a great time. I wish he had told me how he did that.
TDLR: How do I "start" my life?
Go out, put effort into socializing, meeting women and making friends, and finding passions, and ways to get ahead in life
These things will never come to you, you can't continue living the same lifestyle you are now if you truly want change. You have to change your entire lifestyle, how your mind works and views the world.You have to go out and get it, make things happen.
Easier said than done of course, in a similar dilemma, but 23 and moreso lacking on the career/financial aspect of life, and having cool large social circles is something that's always evaded me.
But I will say, at your age I moved to a new state and was able to meet and fuck hotter women than I'd dreamed of before, and make great friends by going out and having fun, a lot, putting effort into socializing. Become more interested in people and try to understand them.
hope this helps
