Everyone is different but i learned to control my feelings since i started to trade a strategy. If you do every time the same, you lose the fear and it feels more like a job.

Trading is not a normal job, sometimes you wait a long time for the right conditions. Investments are different, as a natural short time trader it is hard to sit out a losing position. My personal plan is to ignore my long time portfolio and each month i take a look in it but not more.
