Love own stuff ourselves, deeply. 
We seek approval of what we do. When people do not approve of it for any reason, we doubt our own capabilities. This approach induces negativity. 
First, we must love our creation, irrespective of responses from others. People are engaged in their own activities. They have no time to comment on your work. In the future, they may or may not comment. Don’t bother. 
Second, it takes time to make a product attractive. It demands more labour to make our creation more informative, efficient, and purposeful. As we move onward, we find the deficiencies at a glance, even if there is no comment from the audience.
Third, it’s necessary to talk about our stuff to different segments of people in our circle. At times, we miss the right person who is aware of the values of our creations. A musician knows what music is, and a reader knows what he wants to read. 
Fourth, in this era, people come to know many things just by pushing their fingers on screens. They get answers to all their questions—more than they need. So comparisons are unavoidable. This mechanism provides an opportunity to make improvements to our products. We can’t say improving further is not feasible for what we have created. 
Fifth, branding is imbibed in the minds of the people instantly. The market plays its own role. We have to upgrade our products from all angles. For one machine, the customer is fully aware of the most up-to-date features on the market. We must know the taste of the customers, as per recent trends. 
Sixth, we must learn to appreciate the products of others. When we are reluctant to "like" the products of others, we can’t expect immediate responses from others.
Finally, once we enter the market with our product, look forward and continue upgrading step by step. Never feel we are less than others on any parameter.
