How to objectively reduce exposure at a loss

Pat, So I have been using your service for a few weeks. It is awesome. Thank you!  I notice that whenever there is a new buy I am ready and excited to participate. But when you post cutting 1/4 or 1/2 of the trade at a very fractional loss I get hesitant. I start to think maybe it might bounce, it is an insignificant loss.  This morning I rehearse mentally cutting the small loss with the same enthusiasm as when I am ready to do a new buy (to deactivate hesitation believe).  What do you recommend so I can objectively take the buy/sells? What do you recommend to be neutral about it. Thank You!  Javier
