Well, op you don't need to give up but you have to carefully reexamine what you have been doing and failing, this time do something different and right. You cannot keep doing same thing same way and expect a different result.
Pause!
Learn!
Restart!
Let me take trading as an example. Someone learn, trade and lose. Learn the more, trade and lose the more. Months after months become years and the trader continue to lose. Then if such person stop, there should not be anything like learning again and restart, he should just quit and focus on less risky means of earning. I understood you though and you are not wrong but there are sometimes that you just have to quit.
