Ever notice how some task can acquire inertia? Me too.
When it goes well, it’s like confidence builds and somehow makes it easier to do good work. On the other hand, sometimes uneasiness over a task leads to a little procrastination. Without early intervention, procrastination increases anxiety, and pretty soon the task feels insurmountable. You end up with fear and loathing in… your office.
What to do.

If you presume lifelong change, the prospect of quitting something forever can loom high and cast a deep shadow. Let me be honest with you, the price might well be high. Many things worth achieving demand sacrifice.
To make matters worse, you must pay most of the price before you feel the benefits. There is no bill me later option in kicking habits.
