One and done trade - part of mindfulness

Traded a one and done trade today since I just came back from a vacation and did not get a good sleep last night. 

Part of being a profitable trader is knowing when you should trade at the peak of your game. Like an athlete, if you are not well conditioned for the trading day, for instance being tired, then be sensitive with what your body's trying to tell you.

For me, being tired for the day due to lack of sleep will affect my trading day. Although, I would like to trade further but we should be disciplined enough to stick with our predetermined strategies so it would not affect our psychology which is part of the mindfulness concept. 

This is the reason I sticked with a one and done trade for the day.
