One of the feelings most people lack is that of confidence. And yet it is something we all need to generate if we wish to succeed, regardless of what we want to succeed at doing. Even if you have zero confidence, present whatever you do with confidence, because if you don’t, nobody else can or will take you seriously.
It’s a mistake to attempt to generate confidence or belief in yourself by asking others for their opinion. It will always be subjective and therefore unhelpful, even if it is positive. Why? Because the best creations are novel. Nobody expects them and they usually appear only after a lot of hard work, mistakes, blood, sweat, and tears.
So create your own confidence, lie to yourself if you have to, and don’t seek the permission of others by asking their opinion. Just get on with it and succeed.
