A quitter is someone who gives up on something difficult instead of pushing through to finish it. When a player walks off the soccer field because their team is losing, or a student stops trying on a math problem the moment it gets tricky, people might call them a quitter.

The word carries a sting because it suggests someone lacks perseverance. There's a big difference between making a smart decision to stop doing something that isn't working (like switching to a different sport that fits you better) and being a quitter who abandons anything that requires real effort.

Sometimes people confuse quitting with changing direction. If you realize piano lessons aren't for you and you'd rather learn guitar instead, that's not quitting. That's discovering what works for you. But if you drop guitar the moment your fingers hurt from pressing the strings, then pick up drums and quit when the rhythm gets complicated, then try violin and quit when you have to learn to read music, that's the pattern of a quitter. The key is whether you're running toward something better or just running away from hard work.
