Most times decision making is latter of comparison with already existing knowledge, but mankind is equipped with two levels of interpretation. One is a linear thinking mind that deals with limited information and use around 40 bit processing power. The other is the sleeping subsystem, several millions of bits in processing power that output the solution in time. Most times thinking mind will ponder long terms about it, even when you need to sleep at night and ends up in wrong decision after all by limited background.
So listen what Eckhart Tolle has to told about it, the secret is the used plane to make the decision.
