Lets say, you are committed to do something. You cannot get out of it, and you cannot count on snowstorms to bail you out either. So, now that we've established that you HAVE to do it, you have two choices from here
1) Drag your feet through it. Spend a lot of time "not" doing and then scramble to "Doing". Beat yourself up in the interim. Waste time without even enjoying it. Avoid avoid avoid. Waste time online. Drive self crazy. Think of this while doing that. Think of that while doing this. Worry so much about doing a good job, that you feel paralyzed and throw yourself into an endless loop. Worry- don't perform- worry more- don't perform some more. Sleep a lot, get stressed and eat fattening foods. Finally get there bedraggled, having done a half-ass job, and telling yourself its ok, its not the end of the world after all, there are other things. But, actually, in reality, hate yourself and never stop regretting that you could've done so much better had you not wasted all that time.
2) Have a plan. Stick to a schedule. Do it in small chunks. Focus for small manageable bite sized amounts of time. Reward yourself for every tiny milestone with some internet-indulgence or food or tv. Little by little, in focused efforts, GET IT DONE. Waltz into the finishing line gracefully.
What would you pick? Is discipline really more painful than self-loathing laced time-wasting which you don't even enjoy while at it?
