She asked me, “What is the biggest lesson you have learned from founding your own company?”
Release yourself from people's expectations of your decisions.
If you're looking for people to “get” you or applaud your career-switching decisions, you may be searching for a long time.
The vast majority of people are afraid of trying something new, but–more so–afraid of failing publicly. Most people don't want to be vulnerable and run the risk of closing the doors to a dream.
Your responsibility isn't to handle the naysayers, nor is it to convince others that your decision is right. Your only job is to do what you've been created to do.
You must stand in the rightness of your vision and let your success silence their doubts.
