As soon as you begin to walk your own path, At first they will ignore you. They will pretend you are just joking, or that nothing will come of your efforts.
Then as you pursue your path, there will be those who will ask you to change back. Then they will demand you change back. If you don't, they will either abandon you, or actively oppose you. That's when some will begin to ridicule you. It is now your turn to ignore them. Just continue on your journey.
The hardest thing is when it is close friends that start to ridicule you. Perhaps they are fearful. If you become successful, if you are following your path and I am not - what does that say about me? They might think. Perhaps they are jealous. Perhaps they are simply conditioned to believe it is better to be an armchair quarterback, a small fish, than to actively go after your dreams and make them really take shape. It is not easy to keep walking then, but you must or lose your hope of becoming all you were meant to do and be.
In order to fulfill your destiny, you must be willing to risk it all, to step out of comfort and safety and go on, seeing only your vision and trusting that your journey will be unique and precious.
Happy journeying to all of you seekers! Keep seeking - you will find what you are looking for!
