Normally, I only play either in the morning or the evening, for at most 2 hours (usually less). But sometimes frustration kicks in and I keep playing to reach whatever goal. That's the wrong way to play it, of course. But yesterday I overdid it, lol. Reminds me of my adolescence years, when I sometimes did that.

Good advice, especially the one about closing the game after 3 lost games in a row.
