Don’t say “I’m trying to read more.” Say “I’m a reader” and then go act like one.

Trying is a description of a state, and a state can continue forever without producing anything. Naming yourself as the kind of person who does the thing changes the default, because a reader who has not read today is simply behind, while somebody trying to read more is perfectly on schedule at every moment. The second version has nowhere to fail, which is why nothing happens inside it.

Pick the version you want to be true and behave as though it already is. Carry the book. Read four pages on the bus.
