Since you feel you have poor judgement, I recommend you try these steps:
1) Find some smart friends.
2) When you need to make an important decision, ask your smart friends for advice.
3) When multiple smart people are giving you essentially the same advice, take their advice.
When it comes to advice, "Wise men don't need it, and fools won't heed it. And those who want it the most like it the least."
