I Seem to be loosing my mind . . .

1. It seems like I'm looking my abilities to see moves until my opponent response to my move.
2. I still teach beginning players at the library every week.. . That isn't a problem to me . . .
3. I believe I should start thinking outside of the box when playing match games on line as that is where I blunder, even though its 3 days moves. . . .

4. It's probably my age that is doing it . . .but I know some players older than I am have played well into their ages  . . .

What do you thjnk? .  . .
