Play a system that accounts for this.

Fate gives you fate points to spend when you do t like a roll. It also gives you "succeed at a cost" if your fate points are exhausted or not enough.

You can still just roll with it (pun intended) and die to a random goblin if that's fun. But you also have agreed upon procedure for not doing that. "It looks like the goblin is going to gut me, but (slides fate point across the table) as it says on my sheet I'm a Battle Tested Bodyguard, so I twist at the last second and he misses (because the fate point bumps my defense roll high enough)"

This is pretty easy to import into DND, too, if you like the other parts of it
