The future never comes. When it comes, it’s in the now. The past never happened until you remember it. So you…yes YOU CAN CHOOSE to remember something better if you want to. Be like the unjust steward in Jesus parable (luke 16) that called his master’s debtors and made them reduce their debt so that after his master throws him out, the debtors he helped might put him in their homes.
You or your awareness in the present now is the master. Your mind or thought processes is the steward and your negative memories are the debtors.
