Rambling on life

I know lately I have talked some about reconnecting with friends and family. But what I have noticed with this influx of old friends it has really shown me just how badly I failed at being a good friend or boyfriend or whatever. Times when I could have been selfless I choose not to, or times that I could have done the right thing or followed through on my word I chose instead to do the opposite. I know we all have these moments in life where we have failed for whatever reason being it just out of selfish pride or youthful inexperience and now older I look back on them and see them for what they were instead of what I wanted them to be. I feel as though I'm seeing all those mistakes over again with a new set of eyes and it is helping me to better understand myself and just how foolish I was. I think I am actually a better person now because of the mistakes I made then and thats how it's supposed to be right? Learn from your mistakes? I guess all of this rambling is things we already know just feels good to put it down somewhere.
