These can be even more valuable resources for you, but only if properly processed before placing them in the bank.
First review the memory thoroughly, with intense curiosity and interest, to determine what you can enjoyably learn from it in order to prevent a repetition of the unpleasantness, and to avoid future mistakes. When you have completed this reprocessing, store these valuable learnings in a separate account, segregated from the unpleasant memory itself. Additional interest will be paid for frequent withdrawals, and also when these learnings are periodically sprinkled liberally into your future, where and when you might most want to have them quickly and readily available to you.
Then use this information to plan in detail what you will want to do differently in the future in order to respond more resourcefully if you are ever faced with this kind of situation again. Store these plans in a separate account in the same way that you store pleasant memories. These, too, will earn additional interest when withdrawn frequently, and also when liberally sprinkled into your future.
Finally, process the unpleasant memory itself in the following way to prepare it for proper storage: See the memory far away from you, as a dim and colorless flat framed still picture, as if seen dimly in a dark dusty attic. Store these memories in a separate account, to be withdrawn only as needed for a particular purpose, such as for occasional review for further learning, or to appreciate with pleasure how much you have changed and grown since then.
