Losing one's temper at work is not a good thing and often leads to negative consequences such as getting fired, so it cannot be considered as being at one's best.

Hypothesis: The other day at work, I was at my absolute best by losing my foul temper when I should have remained calm.

Given this context, determine if the hypothesis is true (Yes, no, or unknown)?
