Memories of the past or visions of the future represent only one possibility.  Don’t get caught up in them.  If given the choice between a positive or negative memory/thought which would you choose?  And if all possibilities are the same, does it even matter? Every possible situation leads to every possible outcome.  That means that even if you mess up, that situation can still lead itself to the best possible outcome (or at least one not as shitty as you probably imagine).  The quicker you let go of the situation, the quicker it will feel like change happens.  This allows you to move on to the next situation or moment.  Soon it may feel that everything is just a string of moments.  Or maybe just one big moment.
