Did I grow up too fast? Or are you forgetting to grow up?

Is is bad that I feel older than everyone who isn't in their 30's? I'm sure it has to do with my upbringing, and where I grew up and how God has had his hand on me through the terrible moments of my life. But when did it become okay to be so immature and act as if high school never passed by? Everyone has their moments of acting like children and having fun I understand that, but how can people day in and day out decide that it's okay to "live life" and forget about becoming a mature and respectable person in the eyes of everyone other than teenagers. I don't think people understand me in the least bit and that's frustrating, but all I wish is that people would decide to ditch their childish ways and decide to grow up. This probably isn't the best topic to start a blog off with, but I really do have hope for my generation and I hope writing about it will open up some peoples eyes. We all have different lives and grew up in different ways I understand that, but we all can put the same amount of effort into trying to be more adult like in the things we do. Maybe people will say I haven't lived or I haven't experienced the fun sides of life because I choose not to surround myself with drugs and alcohol and women, maybe because I believe in my heart of hearts that those things will break a man down and ruin him. Living life, to me...is doing the complete opposite. We all have purposes, some will grasp them and others will let them pass by. What will you do?
