I don’t know if you can train yourself to be more driven. Of course, if you’re not driven, you probably don’t care about not being driven. You just want your food and a place to sleep.
It usually doesn’t matter if you win or lose. What matters is that you have the un-ending ambition of getting up after failures or setbacks and driving right into the thick of things again.
Failure stinks, but it’s shameful when you see a man who doesn’t get back up after being knocked down.
I don’t know if you can make yourself a go-getter, or teach yourself ambition and drive, but find a way to do it. It’s a better way.
