knock self-doubt on its ass

 

战胜自我怀疑

 

Don't give up.

 

不要放弃。

 

This is the most important. Don't walk away just because you get stuck.

 

Do you really want to live your life wondering "what if?" No one wants to live with regrets.

 

Think of what you would say to a friend in your situation. Take your own advice.
