If you remove these three things from your life, your life will take a new direction. Number one: self-doubt.
You probably don't know that you are the biggest hero of your life.
When you're going to do something, don't think whether you'll be able to do it or not. Never doubt yourself. Whatever you're going to do, do it with confidence.
Number two: the habit of seeking approval from others. If you take every step thinking about what people will say, remember that no one is going to help you. If the dreams are yours, then the permission should also be yours.
Number three: things from the past. What's done is done. Because if you keep thinking about your past, you'll never be able to move forward. Put your life on forward mode, not on replay.
