Yes, Virginia, there is a Santa Claus. There are also people who are going to purposefully misunderstand you, no matter what you say or do.
These are people with agendas who will commit themselves to your destruction. They want to vilify you. They want to minimize you because there is something they see in you that they want, and believe they can't have or be. Their insecurities overwhelm them, and they look for ways to victimize themselves.
They are jealous,mean-spirited, and spiritually stunted. They are usually passive-aggressive.
They don't have the courage of character to own their words. They will say things behind your back, and will try to sabotage you in your work and home life. They will mimic you and take credit for your work.
Online, they will post status messages and blogs about you without naming you, but when confronted, they'll claim it isn't about you. They'll attempt to make you believe you are paranoid, that you are the one who misunderstood them. They will go out of their way to avoid taking responsibility for their words and actions.
This is why you cannot let them get to you. You cannot worry about what they think or say or do, because it really is none of your business. You don't have time for that kind of nonsense. You have bigger and better things to do with your time. The only person you have to impress is you.
The only questions you have to ask are:
Am I being true to myself?
Am I being authentic?
Do I understand my own motivations and accept them?
Am I living by my own honor code?
Do I like who I am and where I'm going?
If your answers are "yes", then you have nothing else with which to concern yourself. You owe these people nothing, and particularly no explanations. They don't have your best interests at heart. They intend to cause you harm, and it stems from their own insecurities and "no" answers to the above questions.
Keep moving forward; keep your eyes on your goals and your growth. They have nothing for you, and you don't need distractions. They are crabs in a pot from which you escaped, long ago. Where they are petty, be magnanimous. Where they obfuscate, clarify. You cannot be swayed from your goals and intentions.
No explanations. No excuses.
Just keep being extraordinary.
