When I look back at my past, it is very tempting to think that I could have made better decisions, could have done things differently and had a better outcome.

The truth is that the man I am today is the sum of all the things I have experienced, the decisions I have made and the lessons I have learned. If I were to change anything, it would lead to me being a different person... :)
I like the person I am today...so, no, I would not change anything.
