Rule of thumb: The more important a call or action is to our soul's evolution, the more Resistance we will feel toward pursuing it. - Steven Pressfield

Resistance by definition is self-sabotage.

I could be counted upon to perform the mission they had assigned me, or, if that was unworkable, to improvise and turn my men's exertions upon a secondary undertaking as good as or better than the first.

How many pages have I produced? I don't care. Are they any good? I don't even think about it. All that matters is I've put in my time and hit it with all I've got. All that counts is that, for this day, for this session, I have overcome Resistance.
