What you need to do is work on your mindset and see rejection as an invitation to a fight.

Too many people are just too scared. (of authority mostly, of some type)

One of my close friends who is a successful entrepreneur once told me:
‘Try to keep your distance from all the negativity in the outside world. But if you are the type of twisted character like me, use that negativity as a fuel for your work.’

All the successful people (in business),I have met, possess some form or other of that 'twisted character' personality of your friend.
Negative is an energy to be transformed into positive, if you are prepared to do the work.
Thinking back - I don't know (personally) of any 'successful' business people who are just all positivity and light...

Like you said, don't be scared....

Good post!
