Keep busy: Keeping busy with other activities can take one's mind off of worrisome events. Also, have plans. Plan well ahead of time for the possible outcomes, and have back-up plans in case the primary plans fall through. Once plans are made, one can just go out and enjoy other activities. As they say... Que será, será. Whatever will be, will be. The future's not ours to see. Que será, será.
