Who is perfect and who is doing everything right? If I feel scared about any business, I wouldn't start in the first place, I wouldn't need anyone's approval either, I have to believe in myself and I do. I know I can succeed and I will.
All it count is your dream, That will drive you enough to reach where you want to reach no matter what other say. People are skeptical, and that is amount to 95%, that means they are the one's scared to succeed. I wouldn't want to take their place. I rather be with the 5% who believe in themselves to take the high road and have no fear or doubt to get there or already there.
One said " if you want to be a millionaire act like a millionaire" so even if you get scared act like you never scared.
I never had scariest moment in my business, even if it crumbled, I know I can get up, shake the dust and do it again.
