Which commitment should I make?

I want to make one commitment now to save myself from suffering in distant future. The kind of suffering is same as due to unity with undesired situation. For example I might have to shake hands with my enemy. Or I might have to live under poverty. Which single most important commitment should I make to follow every day or every moment or every week so that I may not suffer while getting united with the undesirable? (Answer should be like start keeping right view or start practicing right view or I should start jogging or I should start meditating or start chanting mantra etc...)
