Please Help: Lack of Consistency!

I started my morning very well today with a Live game at Chess.com, which was the subject of my last blog. Later during the day, I played three more games when I took short breaks at work, and did good in each one. That's four well-played games. But before you say good...

Yet, the next Live game I played at chess.com just a few minutes ago was horrible. I'm not saying this because I lost, but because I simply didn't play well. In fact, I'm not even sure if I shall be able to comment on my moves without sounding like an idiot.

I've been observing this pattern about me. Some games I play well and carry home the satisfaction even if I lose. Then I go ahead and play a couple of games shamefully bad.

It has nothing to do with the ratings of my opponents. It has nothing to do with the openings. It has something to do with me, but I don't know what.

Losses don't disappoint me as much as this lack of consitency in my performance does. At times it even scares me, and I start wondering if I can improve at all...

I shall remain indebted to anybody who could throw in a suggestion or two in this regard.

Many thanks.

Prady.
