I believe 35 is a tough age. You've effectively achieved Journeyman level. No, seriously, you're past the Apprentice level, and you've completed all the 300-400 level life courses. You're ready to become a Master. Unfortunately, you need to go on a journey to discover your masterwork. That may take a while. For me it took another 10 years. But trust me, you will find it, if you're willing to take a step sideways in your career a few times to try and find the problem that you seek. When you find the problem, you will recognize it for what it is: Your Masterwork ... something only you can solve. Solving it may pay off financially, with fame, or just emotionally, but either way it will pay off spiritually. You will know who you are.
