Why Resign?

In a good smosition I wouldn't resign because I like good smositions.
Lost smositions aren't worth playing because no amount of smositional understanding can save you at this point.

Do you mean positional?
No, smositional. It is a more precise term for describing complex smositions in transitional smositional smositions.

Just google "smositional". chess.com is the most important source for learning about smositional chess.

Maybe. But grandmasters do this.

What?? No i am not talking about the auto-analysis... do the SELF-analysis option. Maybe things are different where you are from but when a player talks about analyzing his game it usually means looking over his own game from beginning to end looking for improvements, not clicking a button for a computer to tell you a CAPS score.

Resigning tells that we are too afraid to continue the game.
Resigning for me means I am afraid to waste my time. Explain how playing on in a lost position is more instructive than analyzing your mistakes and starting a new game?
One of the big problems with NEVER RESIGNING... is... humans typically learn well by PAIN. If you get LUCKY by coming back from a terrible blunder, you have dampened the memory of your mistakes and you have cheated yourself out of the pain that your blunder SHOULD have caused, and therefore you are more likely in the future to make the mistake again than if you had just resigned and analyzed.
The rating you might gain from stubbornness is only temporary as you didn't get any stronger from your opponent blundering. Bullet chess is different though. I hope you aren't talking about bullet chess. I wouldn't advocate resigning in bullet (without increment) unless you are clearly getting mated and they have plenty of time left.
Well, it's a mathematical fact that you spend longer on each game if you never resign so that would either mean fewer games or more time spent playing the same number!
This shows that you spend less time on chess.com.
