I believe many do adjust to a normal life. Or at least they plan to adjust.

There is a popular girl currently working at one of Sydney's more popular shops who wants to build a small hotel in her home country. She showed me the plans -- 12-room boutique accomodation with restaurant and bar. Looked awesome. Work is due to start soon.

Another girl in another popular shop got a little cross with me one day (a discussion about how she invests her money) and she insisted on showing me her current bank balance. Tap, tap, tap on her phone and she turned the screen to reveal a balance -- in one account -- of $570,000. She had another account for day-to-day expenses.

She said: "Once I make a million, I am leaving this work. Maybe one more year is enough."

I wonder if she will be able to stop once she reaches 7 figures in that account. How tempting it might be to stay on for another year or so and bank another 500K. And if for another year, why not another 2 years and make it an extra million?

When is it enough?
