That's the right thing to do, a plan is a strategy that you will have to follow if you wanna play this risky game, however, if you don't have the discipline to do it, even if you have a perfect plan, it's still useless if you cannot effectively implement it. It's a process, starts with a plan and ends up with the execution and the last part is always the most crucial part.
Discipline plays a big role when you are into this investment. Emotion control saves you a lot of mess.
With good management of your set plan and good disincline with your emotions, everything will take in the right place,
whatever system you have.
I really believe that it's a bunch of combination before you really excel into this business and enjoy all the benefits..
