The ability to wait is the least glamorous advantage available to you, and the most decisive.

A student reading for two hours while the hostel argues about football is not more intelligent than her friends. She has simply priced the future higher than the evening.

This is trainable. Every time you sit with a small discomfort instead of reaching for your phone, the capacity grows slightly. Every time you reach, it shrinks. The muscle is built unwatched.

You are not building willpower as a virtue. You are building the one skill that makes every other skill reachable: the ability to stay when leaving would be easier.
