This is the alternative approach to coming across some early success, this is a difficult route but as you become more self-ware and confident, maybe you can be more decisive? Maybe iteration is the key here too? Setbacks and failures scare me here but that is something to learn and get better at perhaps.

Another question here would be, did you find yourself becoming more decisive with time over certain topics? what helped in becoming so? (I have found myself to very less opinionated about things, that makes this process really tough)
