****Stop comparing yourself to other people
Comparison is a dangerous things to do.
It's like comparison of your past lifestyle to what you are right now.
Some people are in their future already and you are just starting, why would you link yourself up and say you want to be like them.
The reason people don't have what they need is because they want to have everything. And if you have everything in this life you will realize that you have nothing. You can't have everything you want but you can get the best things you need with time. Greediness destroys. There's no way you can have everything and not be greedy for more. Learn to use what is available right for the right things.
