On monuments, single mindedness, and relaxation
Though they're mostly an illusion, monumental moments can be very useful in changing your life and the lives of others. They're an illusion because nothing intrinsically changes about a person just because a monumental day passes. Their IQ does not suddenly increase, their situation does not change, there might not even be more opportunity than there was before. However, there might be a new mindset. At the beginning of a new year, people's minds seem to change about themselves, and they use the monumental turning of the calendar to make it official. There's an external signal that coincides with the internal change and makes it more real. That being said, New Year's Resolutions don't often hold up not because of the monument not being sufficient, but because the mindset never changed. For your own purposes, you have to be able to create your own monuments. At any given moment, be able to return to your reason and decide that your mind has changed. Your mind has changed from hopelessly emotional to reasoned. Your mind has changed from indulgent to frugal. From loud to reticent. From ostentatious to humble. Don't change these monumental moments with excitement, either. Excitement wears off and if that's why you changed, then it will never last. Simply know that there are beginnings and there are ends. Any moment, if your mind desires, can be the end of an old mindset that didn't live up to your own standards.
On single mindedness
Too many of your tasks are becoming fragmented and slow because you are not focused on one task at a time. Look at the task in front of you and only the task in front of you. Close everything else out. Remove all distractions, and finish the one thing that needs to be finished. You have no permission to get up and let your mind wander on its aimless trails of thought until the task is done. Do you truly understand the focus required to do great work? If you cannot focus on the small things, how are you supposed to focus on the grand vision? Practice focus. Practice single mindedness. It's as if nothing else exists until the next minute is won.
What are you relaxing for? A word of caution on rest: You don't deserve rest if you have done nothing to need it. Though it's rare, I've observed as you call for yourself to rest when you have done no work to be tired from. What relaxation do you need? Your mind has not been hard at work and you have accomplished little. Deserve your rest. Deserve your relaxation. Earn it.
