It seems obvious, but usually the answer to your problems is to work hard. Not at the expense of the things that matter most in life, but in harmony with those things. Deciding to work hard means you keep going. It means you are determined to ignore all the distractions and return to a focused state as many times as it takes. It means your ready to face all the anxiety, doubts, and the near constant fear of failure. Do it anyway. Reflection on why you do what you do is healthy, but it can quickly immobilize you. Think about the thing you know you need to do, then make a choice to do it, work hard, and don't look back.
