Realize that worrying has no value, it will stand in your way. It wastes your time and energy, making you less likely to succeed. Face the fact that a lot of things in your life are out of your control, and the best thing you can do is steer all of your focus and mental energy away from pointless anxiety and into taking the actionable steps towards your goals. Practice meditation to develop the skillset and mental discipline that will allow you to focus on taking actionable steps instead of dwelling on stuff you can't do anything about. Always do your best relative to the state that you're in. Optimize your knowledge (by learning and reading a lot), and behavior (by taking the right action according to your best judgement). Beyond that - let go and let the chips fall where they may.
