Regarding fitness, It is said you can not exercise your way out of a bad diet. I would like to say that is also true of the rest of life.
Start with good fundamentals, good premises, a good foundation. This is true of all things, including spiritual understanding. One does well to carefully examine those fundamental principles.
Unfortunately most do not have the inclination to do so. A house does not stand well on a weak foundation.
To enjoy the surface pleasures of daily life, stay true to the depth. Tend to the depth. Pursue an understanding of the depth beyond what you currently know. Strive to live true to that.
The world is not as you have been lead to believe.
