Does a person need a permission to exhibit a God's given talent?

What is really wrong with people? Why is it that people spend so much time fussing over nothing?
Why can't some people just let others be? Can you imaging a talented person stayed up late at night,
cracked her brains on ideas came up with it and executed it only to stay up again suffering the scorn from
Untalented people who only feel sad about themselves because they are not good anyway and they only criticize
what they cannot do.
People fail to understand that, when someone does not seek you advise or opinion before embarking on a journey
or before carrying out a project, or even making any decision, it means the person does not need your opinion or advice
and any advice you try to offer after the whole thing is considered as medicine after death.
