So… stimulate yourself?

> Work on becoming a source of thoughts rather than a consumer of thoughts.

This is the classic “sounds deep but actually means nothing” vague statement that’s only meant to massage one’s ego and try to reenforce an unsubstantiated idea in a faux-philosophical way.

You are always “sourcing” thoughts even when “consuming”.

Being able to sit still, quietly without having to stimulate oneself is, by all means, exactly that: avoid stimulating oneself. Looking around and trying to come up with small stimulations based on your surrounding is merely replacing one object (say, your phone) with another.
