What should you do when those around you don’t believe in you?
You should find a different group of people to surround yourself with. If the people that don’t believe in you are friends and family, limit your interactions with them, tell them they’re wrong and more importantly believe n yourself and prove them wrong.
“Some are destined to succeed, some are determined to succeed.” ~H.H. Swami
You tend to become who those closest and most important to you think you will become. Choose those that are most important and closest to you wisely.
