There's no shame in admitting you got outplayed

It's a simple fact of life that there will always be someone better than you. In fact there will always be hundreds of people better at what you're doing than you. Despite what your parents told you, you're nothing special, and in all likelihood you never will be.

This being the case, when you're playing the most popular online game in the world, where the number of players is in the millions, there are always going to be hundreds or even thousands of people who are better at the game than you. They might have more time on their hands to practice, they might be more determined to win, they might have a lot of experience with MOBA-type games, etc.

The point is they exist, and there's a good chance that you'll end up playing against them, maybe even every day. So when you find yourself getting stomped by your lane opponent and cast around for a reason as to why you're sucking so bad, just remember that it might not be that you're as trash as you think you are. Your opponent is simply better.

And here's the important bit: there's absolutely nothing wrong with that. As long as you realize that you're not God's gift to League of Legends, there's always room to improve. Whenever I play, I play with one policy in mind: if I come out of a game and can't think of anything I could have done better, then I re-watch the game and find one. http://www.replay.gg/ is great for this, but there are other more reliable programs available too. I watch the game over and over until I find a mistake, either mechanical or strategic, at which point I think "ok, I'll work on that next time, here's how.........blahblahblah".

IMO there's no such thing as a "perfect" game, one devoid of any misplay or mistake that could be improved upon. It's part of being human that we make mistakes, and part of what makes a human intelligent is our ability to recognize that we aren't perfect, that others may have knowledge that we don't. And if we care at all about what we're doing, it is our duty to find and correct those mistakes, not in an effort to BECOME perfect, but rather to STRIVE for perfection, even knowing that attaining it is impossible.

So if someone on your team is dying a lot in lane, it's important to realize two things:

1. That bad games happen, and no one is perfect
2. That you're no prize yourself. Everyone has someone better than them, many in fact.

And it is a poor excuse for a person who blames another for being inadequate when that individual is simply trying to learn how to become better. That is all.
