Many things actually.
A big one is building up my personality, being on the outside the person I wish to be on the inside.
I don't think I was able to do this very well, I think I may not know how.
It may be that the person I want to be just isn't me, but I will continue trying because at the moment, I cant say that I feel at home in my own skin or in my own mind.
The person I want to be will.
Another thing is traveling. I wish I could have done more traveling, I always wanted to live a life of traveling around the world but never did. I may not even like that kind of life, if I would have been able to do it 5 years ago, I would know if its even the kind of life I want instead of always dreaming about it.
What if I actually do it and find out its not what I want? What would I have given up for it only to find out that I don't want it?
They say the things we regret the most are the things we didn't do, this is especially true for me.
The list can go on, but, ill add just another one:
I wish I would have built up more courage, I think it may be the main thing that holds me back in life. I lack the courage to do what I feel is right, to do what I want to do. I wish I would have understood this 5 years ago and worked on improving it then. I don't know if it would have made a difference today, but at least I would know that I tried.
