The truth is that 9 times out of 10 people are only going to be loyal as long as it benefits them in some way, and you have to make sure that you remember that because trusting the wrong people with too much of your heart is almost always going to end with you feeling betrayed.

Don't overestimate the loyalty of the people around you and don't underestimate your ability to know when someone is being disloyal and be ready to dismiss them at will.
