Don't be afraid,no one can spoil anything of yours. People will scare you, remind you evertime that it's hard,tell you it's impossible, discourage you by saying you're not capable of doing. They'll give you thousands of reasons why you should not do. Just find one reason for yourself ,why you should do,that would be enough to defeat all negativity around you.Focus on yourself and avoid those people. People who achieve success are among you. And people who discourage you,have never ever tried to fulfil their dreams. They'll put on your head that you can't, your every failure will be there opportunity to discourage you more. Don't listen to them.Everytime you fail, you rise. Motivate yourself every morning when you wake up, think of your dream when you wish to give up. And more importantly love yourself and your dream.
