emotion invest

sometimes and many of time i feel that i do feel angry, mad, worry for something that already passed. i called that emotion investment: for plenty of time that investments were sunk cost, you do feel stress without do anything better. what done is done, bygone cannot change. so how ever do invest your emotion in the right places. look forward for what consequence with ease and do best to go next step, better than worry for what done and what still not.
