To have tried for something but not really given it full attention or effort is a cowardly move, a defense mechanism so that when it doesn't work out in our favor, we can tell ourselves it's just because we didn't really try, and that if we had really tried maybe it could have gone differently. Don't give yourself that easy way out.
Actually being capable of doing something (as opposed to merely theoretically capable of it) includes an ability to consciously avoid that excuse, to fully take on all the complication and challenge that comes in the details of getting something done right.

Have you ever seen someone turn the tables on an overpowered ganker? Upset an expensive net-deck with their patchy card collection? Overcome lag, poor game balance, a dropped connection, an interruption, or bad luck?
It's spectacular. In-game skill defeating meta-game or extra-game injustice.
The hardship isn't fair. We should remember that, should cry for a balance fix, for cheaper cards, for Comcast to stop throttling our goddamn connection when we're playing Dota.
But in that moment, in that game, with no mid-battle patch coming, the only way to win is to beat the odds. To work when you're sick. To go on a date when you're exhausted. To get to the gym when your car is broken, your schedule is packed, or your friends stopped going. To adapt.
