Introductory to two systems
System 1 : based on experience to learn and improve. Functions on intuition, automatic and rapidly without any control.
System 2 : requires effort full thinking. Requires reasoning and most important concentration.

If we behave in a certain way, our thoughts and emotions will eventually catch up, we can behave our way into feeling.

Stay focused on hard data before you, base your decisions on critical thinking and nit subjective belief. Or you will fall into the trap.
Even in making the major life decisions where in ask ourselves about the actions we are doing. We feel more comfortable asking simple but important question. For eg
