Your only limit is you...
We all have a past, we all have skeletons in the closet, we all have fear of people seeing us for what we may have done or who we really are. We are all guilty of wearing a social mask at times and we are all at times judgemental of ourselevs and others.
This is all ok, this just makes us human. Today is a new day, the past is the past and tomorrow is yet unborn so today is all we have. Don't limit yourself today, don't live in the past and don't fear judgement. What doesn't break us only makes us stronger and we all have it within ourselves to live to our fullest potential.
