Your standard of excellence is directly related to your degree of skill and perfomance in each area of your life. Often we believe our competence to be greater than it really is. Be honest with the scale by which you are measuring yourself. If you have some proficiency, then you are meticulous compared to an amateur, however, you are a slob compared to a master.
By going all in, you raise your bar. Whatever you discern to be your minimum level of acceptably by default becomes your standard of excellence. The journey towards mastery is a seemingly endless road, but the destination is not the point, is it each step on the path which makes you better.
