"Life is like unto a long journey with a heavy burden. Let thy step be slow and steady, that thou stumble not. Persuade thyself that imperfection and inconvenience are the natural lot of mortals, and there will be no room for discontent, neither for despair. When ambitious desires arise in thy heart, recall the days of extremity thou has past through. Forbearance is the root of quietness and assurance forever. Look upon the wrath of the enemy. If thou knowest only what it is to conquer, and knowest not what it is like to be defeated, woe unto thee; it will fare ill with thee. Find fault with thyself rather than with others."
"The strong manly ones in life are those who understand the meaning of the word patience. Patience means restraining one's inclinations. There are seven emotions: joy, anger, anxiety, adoration, grief, fear, and hate, and if a man does not give way to these he can be called patient. I am not as strong as I might be, but I have long known and practiced patience. And if my descendants wish to be as I am, they must study patience."
I think in the big picture, patience is the way forwards, the way to win. You take small actions each day towards getting what you want. But, I think it's critical to guard your time from nuisances and distractions. In micro, on the minute by minute level, I think being impatient is the better way - look to fill dead time with learning, dispense with formality and bureaucracy as quickly as possible, talk about things that matter instead of smalltalk and pleasantries, break away from organizations and people that don't respect your time. In macro, in the big picture, patience and steadiness is the way. In micro, on a day to day level, impatience is the way.
I like how you put this and can relate. Impatience helps me be productive. In some cases when my computer is slow, I'll be impatient and I'll multi-task. I'll get something else done while I wait for the computer. So here I agree that impatience in micro is productive.
However - if you're constantly looking to fill small gaps of time - that kind of thinking can stress the brain and wear you down. Looking to fill time gaps is a management task for the brain, not necessarily a creative one. For me, management tasks usually sap my energy.
