Don’t let the voice of critics paralyze you.
Believe in yourself.
You can do anything you set your mind to.
Criticism should always lead to improvement.
If the result of criticism is otherwise than that criticism is not healthy.
Close your ears to it, just check the path you are going is not wrong and carry on with your goal.
Have faith in your ability.
All big achievers were each, once, the favorite target of critics 🙂
