We tend to perceive aggressively what is unfamiliar or incomprehensible to us. So don't be offended by your old environment if they react negatively to your new activity. This is simply a result of their lack of understanding of what you are doing. 

Instead of taking it as a personal insult, accept it as a natural reaction to the new and unknown. In time, perhaps they will understand your path, and if they don't, it's just confirmation that you're moving in a different direction where their understanding is no longer as important.

Embrace your journey and focus on what fulfills you. Understanding often comes with time, and those who truly care will make the effort to see your perspective. Keep moving forward with confidence.
