This question is semi-philosophical, but I recall my ex-classmate she had quite rich parents and really didn't need to work. As an only child, she had everything first (all technology, all pricy vacations, they even bought her own flat in 18 + car). Since she had a lot of money from her parents and a lot of free time, she only enjoyed life (some dr*gs and other stuff). As a person, she didn't look like someone who would appreciate money or time at all because it was "normal" to have everything from all above mentioned.

(And I don't want to sound bad, but I honestly don't know what skill she would have that she could use to make a living - the only thing she was really good at was being sassy, which, oddly enough, earned some people's respect.)

Validate your Idea before spending months
building something nobody wants

we all have been there, spending months and months building an idea that we thought was brilliant, but nobody cared
Validate first then start building.
