A few mistakes and there goes my career

I'm a young man that made some mistakes growing into a man,and now I'm being held accountable for the decisions I made.

Although I'm a hard worker my attempts to refurbish my career went unnoticed,now I'm back to square one!

My motive is to find another company that's willing to take a chance on me,I'm content with hard work and ready to get back to it...As far as my criminal background goes I've never been convicted of a crime but I have some cases on me (not pending)which leads to unemployment.

I have over three years of experience and looking for a open position with room for advancement.
