David,
You are in an awesome place right now. You are dissatisfied with your life, and you have the insight to have determined how you are contributing to those feelings. This is far further than most people get with three times your years! Start asking yourself questions such as “what is something I can do to change ______” or “what do I really want to happen with ______” and “what do I need to do or learn to make my life into what I want it to be” you won’t have any answers, but you are bright, and the answers will come, along with the changes you will need to make to move forward. Good luck!
