A major point to understand is that the world contains everything, literally everything. There’s good, there’s bad, there’s appetizing, there’s gross. People have different tastes and the world provides for them all. This being the case, you must ignore what doesn’t align with your palate while focusing on aspects of life you do enjoy.
For instance, in your life, you’ll fail and you’ll succeed, you’ll experience both loss and attainment, you’ll fall and you’ll rise. As part of the everything of life, you will come into contact with the unpleasant. But to concentrate on such things is poisonous — instead, concentrate on that which inspires you.
