it depends on the life you want to live and the "comfort" you want to have.
Anyway you will have to work for it.
If you want to save enough "money" to afford it.
There is 2 ways to see it :
- Have a job you like and work enough to live a simple but happy life.
- Have a heavy work that you don't do for a long time to save money for the future time you will stop working.
There is no perfect answer there, it is up to you yo choose the one that suit you.
