(Respectfully asking) I am from India want to ask Indians or people who are not Australians but working there as a waiter, or a bartender or whatever. Are you satisfied with your life? Is there contentment?

I am asking this very respectfully (and before some aussie get racist i want to add no i do not want to come to Australia i am just asking because my friends are there ).
I know there work pay and work life balance is quite good and you can earn decently in per hr basis in service places. And i also know that your next generation's life will be well set for sure because of your hard work.
But are you guys content in life? Do you sometimes feel purposeless in life? Do you want to do more things like life which are more impactful?
Just wanted to hear the perspectives of all those immigrants who left their country to work somewhere emotionally how do you feel?
