The decision to ignore the doubts from family and friends and to take a completely different route in life was the scariest choice we have made. I've always been told that starting is the hardest part in progress and in the words of Gary V "fear kills growth". Taking a leap of faith is often seen as a risk, which means the same people who think this way put their faith in never moving forward. You should trust me when I tell you to jump.
The best part about following your heart is living your life with complete freedom. If you honestly love what you do then you never work a day in your life. I can understand if you don't quite yet know what that passion is, but when you find it, don't let anyone tell you that you can't succeed.
