"Giving up when things get too hard" is a gift in itself. Not everyone is good at knowing when to stop.

I'd say that applies extremely rarely. When success depends on putting in the work (which is most often the case, especially if you have a higher aptitude than most), giving up easily is a major impediment.

I say this as someone who had this problem myself. Always being told "things come so easily to you" made me immediately avoid everything where I didn't excel out of the gate.
