I'd rather have an additional source of income growing every day than to see some foreign country filled with people living in poverty just so that I can come back and tell all my friends how 'changed' a person I am.
You make a good point about the "have to travel NOW" mentality. My brother is travelling and living over in the UK. He's 25, has no real job, has a 40k odd student loan and no savings. When he comes back to NZ will have no career really to make decent money. By then he will be 27 ish.
I'm 22, if I stay in NZ and work on my career, I should have a few decent assets under my belt, be earning a decent wage and will be light years ahead of him and most of the other people I know.
Really opens my eyes to how going against the crowd generally works in your favour in the finance world.
I work in a bank here in NZ and it amazes me how much debt young people are carrying with little or no regular savings at all. Then they complain that they will never be able to afford a house deposit (yet they can afford overseas trips, concert tickets, new cars, etc)
