There is no wrong in not letting people know your next move. Cause, people who are insecure will see no shame in trying to pass those insecurities onto you. You will never be short of people telling you how and why you cannot or should not do something, they will shower you with obstacles and challenges supporting their fear. However, let not their fear become your fear.
Don’t let anyone’s insecurities stop you from living your best life. Be fearless and enjoy your passage on this earth.
