Becoming psychologically bulletproof means you have nothing to hide. It means you have no ghosts in your closet. It means your past is nothing to be ashamed of, and your future is nothing to be embarrassed about. What it really means, is that you’re progressively living your life by choice, not out of fear.

You have to choose what you want to do and who you want to be. You have to manage your mind and your time. You can’t continue to justify living beneath your dreams. You have to really want it. Because once you do, nothing will be able to stop you from having it. You have to let go of your bad habits. You have to re-arrange your priorities. You have to say “No” more. You need to put first things first, every single day. You have to pay the price.

If you’re willing to pay the price, you can have absolutely anything you want.
