Many times day traders are very anxious and want to be involved in a trade all day. The market only gives a few good opportunities a day and that is when traders should react and take what the market is offering. 
Trading is very similar to the lion in the jungle. The lion stalks his pray in the brush and he does not pick on the strongest animal in the pack. He looks for the one that is wounded or the animal that is not paying attention. Therefore, as a trader we must do the same thing. 
Patience is what pays. Patience is what gives the lion a full belly when he has not eaten all day. Take a page from nature and only take the best chart setups at the most opportune times. As a trader we cannot impose our will on the market we can only take what the market gives us.
