Take a die with six to twenty sides and assign a belief system/worldview to each number.
Roll the dice twice, first for the belief system/worldview, the other for the number of months you live by it.
Of course, you can vary the parameter according to your taste and courage.
But it is important to persevere, so you better start small.
I call it Rhinehartian chaotic paradigm shift.
Dice Man goes chaos magic.
