One of the fundamental ways to become better at anything is "Reflecting", more about it here.

So here is something you may want to start your year with,

Think about the following two contexts and the questions linked with it

Context 1 - Think of -

What kind of feeling that you like to end your trading day with? -> What kind of behaviors lead to that feeling? -> What kind of scenarios lead to that feeling -> How often do such scenarios occur? 

Context 2 - Think of -

What kind of feeling that you "DON'T" like to end your trading day with? -> What kind of behaviors lead to that feeling? -> What kind of scenarios lead to that feeling -> How often do such scenarios occur?

Thinking of the above two contexts will solve many if not all of your trading issues.

All the very best for the coming trading year!
