“In order to do X, you must do Y.
“To get the most utility out of X, you should really follow Y with Z.
“But wait, now isn’t a good time to do X. Here’s this other really great opportunity, A, you should do that first.
“Logically, you should do B too, because nothing replaces experience.”
Such limitations may be internal or external. Internal factors are tough — We must first make the decision to want to do X. External factors seem beyond our control — How do you grapple with the way things have always been done?
Regardless, it is always important to ask, Why?
Why not do X now? Why wait?
