Things happen for a reason

Feeling insecure at times is normal. But I have issue with it because I tend to feel insecure at most of the times. Maybe it's time for me to change my mind set and appreciate myself, people around me and live the life  to the fullest. I need to bear in mind that no one is perfect and there must be a reason for things (bad things or things that we don't like)  that happened to not just me but us.
