I once read that there are two types of people, people who hear from others they “can’t do it” and say to themselves, I guess I can’t do it, and then the other group says to themselves, I will show you I can. Supposedly people who are very successful are in the latter group. I kind of believe this. My husband never listens to the negative voices and he is much more ambitious and successful then I am. He is confident in himself and likes to prove other people wrong. When he decided to come to America for college, his family laughed and said he would never last on his own and could not understand why he would go to school here. When he chose his major they laughed at him and thought it was a “girl” major (he majored in HR) and now he is VP with a masters in International business paid for by his company. He is the only child in his family who completed college and he has done very well in his career. Their comments were very hurtful, but he persevered and now they see he was the one who has accomplished everything he has set out to do.
His family was negative, but they didn’t know what they were talking about. That’s another thing, usually the most negative people have no idea about the thing they are commenting on. Try to only speak to business owners who have been through similar experiences, not someone who has no idea what it is like to own or start a business.
Believe in yourself, and if the business does not work it will have been a time of learning for the next project. Learning new things almost always costs time or money or both. Most successful people have learned through making some mistakes, so don’t pressure yourself with doing everything right, just try to look at it as a time of learning and look forward to the future.
It sounds like you are getting positive responses from your original question, pay attention to those.
