I’m still working on this so forgive my lack of eloquence but I believe awareness makes you act: Fully understanding how the next 10 seconds of your life is to be spent will require (cause, motivates) you to spend it that way. When there are no questions left about what needs to be done or why, you will find yourself in a moment of action.
Believing that a thing needs to be done right now equals doing that thing.
Merely believing that it would hypothetically be nice to do is not the same as this.
If you believe something must be done, you will be doing it or working towards it, right this second. To be unmotivated is to be without knowledge of how to act and hence without belief that you should.
