i attribute to Discipline. there are many things you know you should do (or not do), but it takes a "new" mistake or repeated mistake to remind you about your original plan.
to some people, there is no way out .... it requires "pain" (as in losing big money) to be finally rid of one mistake/bad habit. then there are other mistakes and bad habits ....
A lot of "traders" are really in it for the action, but kid themselves by telling themselves it is a way to make a fast buck.
The $1k you lost shouldn't be a problem to you if that is your uncle point. I always know how much it is going to cost me to make a trade before I enter since the stop goes in first.
