One way I think to mitigate this mind game of fear of failure/rejection is work on what you're "passionate" about. The word "passionate" is abused a lot but in this context I mean work on something you know you want to work on and genuinely enjoy doing. As a result hopefully you won't give a flying F about what others think or whether you've achieved some artificial benchmark of success. Consequently, the lack of self doubt that passion affords you will likely give you a greater chance of achieving great things as a side-effect but again thats not the goal.
Its the living up to rubrics, expectations, and some mold that really can put a damper on life and make you susceptible to these mind games. If your doing it, give yourself a break and recenter - life is too short.
I dont think being passionate about something helps in this context. You could be passionate about something but as soon as people eyes on your product, you'll still go back into fear-of-rejection mode.
