Signs you're destined for greatness (or utter failure)

You play chess...alone. Now I'm not talking about playing the computer here. I'm talking about having a chessboard out, sitting on one side, making a move, and then walking to the other side to respond.

You've stood at a bridge and thought of jumping. This may sound macabre, but the greats have all lost it all at one point, contemplated suicide, and then come back better than ever. The trick here is to not, in fact, jump.

When you're alone, you pour two drinks--one for yourself and one for your imaginary opponent. Note: This sign includes clinking glasses in acknowledgement of your adversary.

So far, I've done two out of three. I'd like to think I'm on my way. To what, you say? I'm still uncertain.
