Whilst rejection does not feel good, and it is easy to take it personally, especially when you own the business and have spent months or years building a product or service – I believe that it is necessary in order to be sustainably successful in the startup space.
Are you in business to make money, to have fun, or to inflate your ego? If it’s the latter, then make an appointment to see a psychologist before your business fails, and most likely your ego with it. Sure. Once you have a good business I’m not denying that it IS something to be proud of, however if this is a big part of the reason that you starting a business in the first place, then you are getting into it for the wrong reasons.
