Finding the approval of your actions on others alienates you from yourself.
You fear that others do not perceive your thoughts and actions? Are there situations where the fear of what others may think or talk about you, kept you from affirmative action? I bet you nodded: "Yes."
Time to change your mentality.
Today, the only person you should strive to get ahead in development, is a person that you were yesterday. Prove something to themselves, not others. You are good enough, smart enough, attractive enough and strong enough. You do not need other people to validate your money; You are a valuable person.
If someone tells you "no" or if someone says something negative about you, it does not change anything and you do not have any relation to your internal qualities. The words and thoughts of others have no real relationship to you, to your values. Of course, it may be useful and desirable to make a good impression in certain situations, but this is not the end of the world if you come across negative or refused. Negative - the problem of those who distribute it.
Great to get a positive result of the impact, but it does not always happen. And that's fine. You must understand that your worth does not depend on the views of others. When you are going to really change life, there will always be those who disagree with you, those who ignore you and those who directly and blatantly deny your ideas and efforts. Make confident step forward, do what has to be done and let others think what they want.
