Habits resist change. We should plan to deal with that. Whether you're resisting a bad habit or nurturing a good one, expect the resistance and use it like a cue to push on through.
At the moment when you want to avoid it, pause. There will be a moment (or a bunch of moments) when you think, “Oh, I’ll do it tomorrow.” That’s the moment you have to not let pass idly by. Stop yourself, and just sit there for a moment, not going on your computer, just turning inward. What are you afraid of? What’s stopping you? There is a discomfort you’re trying to avoid. Instead, smile, and start. Do it and enjoy it in the moment. You’ll love it.
