Had a good time.

Not bad, but look what I achieved:

10% - eating.
5% - listening to some garbage on YouTube.
5% - listening to music.
1% - playing Mafia.
79% - feeling depressed.

A person is optimistic 40% of the time.

No, if they're not feeling depressed the rest of the time, it doesn't mean they're optimistic. It just means they're not feeling depressed.
