Don't care what anyone else thinks of you. Get clear on your thoughts around giving a concern about what anyone else thinks. That will create fear in your life and that will keep you small.  

What anyone else thinks has nothing to do with you and everything to do with them.  I mean, if there is someone in your life who has exactly the career path that you want, and you want to go to them for guidance or advice specifically around who to be as this type of a businessperson, that's one thing.  

But to start up a business and go to your friends for thoughts on it and have them all tell you that it's not a good idea, or it stinks, or this, that or the other thing...  

Unless they have what you want, or they have experience in this area, then don't even go to them. I would really just disregard it.
