Have A Plan

In trading, as in life, you need a plan. This plan includes not only the micro – a strategy for each and every trade you make – but also the macro – meaning why you trade, how you intend to reach that goal (your means to the desired end), and what you’ll do as an alternative if that doesn’t work out.

Know what you want to accomplish, how you intend to get there, and what you will do if it does – or does not – work out. Have a plan and stick with it. That works in trading, as well as in life.
