A creative passion of mine is writing. An omnipresent enemy of mine with which I have many battles, is Resistance. Resistance takes many forms - excuses, other work (a form of excuse when you get down to it), friends, family, half finished ideas that get sabotaged (by resistance), lack of ideas, checking email, twitter, etc - in fact another word for resistance might be Excuse.
A great book on the subject of resistance, recognizing its many disguises and developing strategies for combatting it, is Steven Pressfield's The War of Art - you can tell where I live from that link! Read, re-read it (I am right now), and keep it beside you even if just to remind you what you are up against.
If you are wanting to do some writing practice - writers need to have a regular practice just like a long distant runner or serious meditator - and resistance is rearing its ugly head in the form of no ideas, try this Idea Generator. Just don't hit the reload button too many times becuase ideas don't speak to you…that's just another form of resistance!
Oh - and don't say that this doesn't apply to you becuase you don't like writing. Resistance appears in all aspects of life. Be warned. Be vigilant!
