There will always be naysayers. There will always be people that don't want you to succeed. They may even be people that you expected to believe in you.
You see, there is no "bandwagon" when you're just getting started. People won't want to hop on board because you're not the "next big thing"... yet.
I would suggest two things:
- Do great things even in the face of naysayers. They aren't going away.
- When you succeed, remember those select few that supported you. They are the ones that truly believe in you.
