Good business

The most devastating experience in life is that of feeling worthless. 

All creatures have their lives rooted on survival ,except for humans,whose lives are driven by purpose.

For example a good tree is that which has managed to grow and produce fruits in due season,it doesn't matter if it's fruits get consumed or not.

Whereas for us,it's how much our labours are recognized and appreciated that matters.It doesn't matter how much you work,as long as you don't get the rightful honour for your actions,you are as good as nothing.

In business,the value of a product does not depend on what you are selling,but rather by who you are selling to : for example a packet of sugar in a poor community might cost twice the price in a wealthier community. 

The way you feel about yourself is determined pretty much the same way. It's not really what people say about you that matters,but more about who is saying. 

Trying  not to care  about what other people say will not make you feel any better about yourself,because as long as someone means something to you,what they say will always mean something to you.

Therefore before you go out of your way,trying to improve yourself,first make sure you are selling your efforts to the right person. The right person is the one who will always give you the honour that you expect for your efforts, everyone else is a bad customer and will destroy your enterprise.

I know you have already started thinking about all the people in your life ,but your worst possible customer is yourself. Learn to celebrate yourself first before you can start expecting anything from other people. Be proud of  your effort,and honour your abilities more than the results of your actions.
