Learn to Trust others, but as a Last Option!

When you proceed with a blind trust, you are holding the sword by its blade, it will cut you hard.

When you proceed with caution before trust, you are holding the sword by its handle. In the moment of crisis, at least you will get a chance to defend yourself.

Honesty and loyalty are two very expensive virtues; you cannot expect it from everyone. The world is full of cheap people who would not mind putting conscience aside for a little extra gain. Therefore, learn to trust, but as a last option.
