No matter what route you take, no matter your stance, efforts, or passion - someone will always have a problem with you. If not with you, your idea(s), your attempt at execution, or any other small piece of the puzzle you're trying to accomplish.
You will face failure. You will face ridicule. Very few will ever understand you or your 'why'. In your times of lowliness, you'll be frustrated, beaten, unmotivated, and depressed.
It is then you will show the world what you're made of. You can choose to sit in wallow in the negativity or ugliness of your critics or you can rise above and fight until you become victorious. No great deed or accomplishment is ever easy - it requires work, failure, and is almost never achieved at attempt #1.
Be tenacious. Be persistent. Be kind. Never give up. And be COURAGOUS.
