Do not take things on the face value. No matter if you read something, hear something, or see something, do not accept unless it is backed by solid proof.
When things aren’t proved, go, and question, and if you aren’t satisfied with the answers, the next step is to experiment and experience things yourself. When we experience, we know exactly how it is.
Be wise, though, when you follow this strategy. Put time only where finding the answer is worth it.
