I am 26 now and I regret for not having fun. All I did was play games all day in my room. When I see teens and early 20s having fun, travelling getting laid I really feel jealous because I never had that. I have no friends and no girl ever showed interest in me. I get jealous when I see people having fun like partying, travelling with friends, it just hurt me so I had to delete my social media. Now I am 26 yes I am still young but now I feel more like young adult instead of young and free. Most my friends get laid easily but I can't, maybe dating is not for me. I also failed other aspect in life I still live at home and no degree no car. So if you reading this and your in your teens and early 20s please get out of your comfort zone, go talk to people, talk to girls, travel if you can, and make lot of friends. Trust me you will never get another chance in your life.
