How do you remind yourself of the value of your time and money?

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.)

On the other hand:

– There are still people who can achieve something from nothing

– They can have such a bad situation that they are forced to do something with their existence

When it comes to me, whenever I had to do things I disliked or found difficult – like learning a new skill to earn money – I ended up valuing both time and money much more. I also started appreciating other people’s time. The easier things come, the less we tend to value “fast, easy” money and the time spent getting it.

Is it good to earn things the hard way to appreciate your time and money? How do you recall its value?
What's your stance on it?
