There can be a tendancy for people to think that other people are as interested in their product as they are, which isn’t always the case.
A person’s new product is their baby, but not necessarily so for other people.
Other people don’t live for your products, and sometimes people don’t have the sense of reality for what other people really want – what’s important for other people.
Therefore sometimes you have to calm down and understand that it takes time for other people to get as excited about your product as you are.
Even if you’re not good at what you do, you only have your own sensibility and taste. Don’t think that your point of view is the only point of view. Your idea is your baby, not everyone else’s baby. Listen to other people and be humble – understand their point of view.
