Gonzalas,
I agreed with BlueEagle, IMHO there are many ways of moving forward, however there is only one way of standing still. In all our living years, we made some mistakes, we received certain rejections. We can't whine at it all the time, nor even in the future. Pick yourself up and move forward, learn from your mistakes. Knowledge is only useful and critical, when you have a tough decison to make.
Good things don't come easily my friend. Go for it!
