Patience is the most valuable trait of the endgame player. In the endgame, the most common errors, besides those resulting from ignorance of theory, are caused by either impatience, complacency, exhaustion, or all of the above.

I remember being with a girlfriend who asked me to look over some chess openings with her. I instantly fell asleep. I found that I could always take a nap in any situation by just looking at some opening variation - my eyes would shut right away.

Patience is the most valuable trait of the endgame player.

The business of the endgame is maneuvring to control critical squares, advancing or blockading passed pawns, preparing a breakthrough by the king, or exploiting the subtle superiority of one piece over another.

Sometimes players need to gain time on the clock by repeating the position, but most often its purpose is to wear down the opponent psychologically.

I always urge players to study composed problems and endgames.

Agreeing to draws in the middlegame, equal or otherwise, deprives you of the opportunity to practice playing endgames, and the endgame is probably where you need the most practice.
