Marking to Market Our Lives

I was wondering on how much we can learn from the stock market things. Take the daily marking to market system. If only we could settle all our thoughts/worries /desires etc. on a daily basis by marking them to the latest realities and closing out all stubborn positions, how wonderful our lives would be! Let us at the end of each day, pat ourselves on the back for our good work done and regret and dabble in self pity for our blunders -but ensure that all positions stand closed out fully. Then each day would be a free new day, without any past baggages --nothing to worry about-no regrets or self-pity, no need to make any overt or covert efforts to show one's achievements/talents---!. Life would then be like a soldier's on the warfront who lives life by each day and fully enjoys the spoils of each day!
Like what they said in the Bible -' God has given this day- let us rejoice and be glad in it'
