RPG suggestions?

Whenever I play Fire Emblem, I always save scum.
If a character dies and they're not supposed to die for the story, I restart the battle.
No exceptions.

This is actually much harder than it sounds, as many times I'm at a point where I can easily finish the battle, but I just happen to lose a guy withing the last three or so turns.
Quite frustrating and time consuming, but I know it'll help a lot later in the game.
