When trying to achieve a goal, don't put your trust in someone else to help you achieve it.
Don't make assumptions that they know what is best for you and they have your best interest at heart.
The lesson here is to cover your ass in this situation. By all means, life would kind of suck if you couldn't trust others. The biggest takeaway is don't allow it to be at the expense of you not trusting yourself.
Need to work on this thought. Mad incomplete.
