Your new mantra:

Que Sera, Sera,
Whatever will be, will be
The future's not ours, to see
Que Sera, Sera
What will be, will be.


When devising a new tactic, stop and say the mantra. When infuriated about the situation, stop and say the mantra. When sadness sets in, stop and say the mantra. When your mind succumbs to thoughts about what is going on, stop and say the mantra.
