Are you kidding me? The thirties are actually the best I think. My thirties have been so much substantially better than my teens or twenties, I can't even imagine why I wouldn't want to be in this decade of my life. Teens suck for a lot of people, but I can look back and say I was the most blind about life I had ever been in my 20's. Here is the thing though, I didn't have a bad 20's, I would say it was a good time in my life and no different than anyone's life at that time. College, girls, relationships, jobs, etc. But you really mature out and gain real perspectives on life that are just impossible in your 20's. I would say that in your 20's, the average person has the most fucked up priorities. You feel really strongly about things that you learn don't matter that much at all. As your emotionally chill out, your life gets a whole lot better. And through that, you even gain a better appreciation for everyone's perspective, not just this group of people or that group of people, I mean literally everyone.
