1) Use my spare time to study a more lucrative field, and negotiate a four-day work week. The pitfall here is that I need to spend all of my spare time working, so that I may be able to work less in the future (and it’s not guaranteed that I will).
2) Move to a country where the cost of living is cheap, and freelance with international clients. The pitfall here is that I have to move away from all the people I care about. I may also end up introducing more stress into my life by living as a foreigner and relying on a freelance income.
3) Invest all of my time into starting my own business (for pitfalls, see 1).
4) Negotiate a four-day work week on my current wage, live a much more ascetic lifestyle, and only save a small amount of money for my future.
5) Marry into a wealthy family.
6) Find a duffel bag with a few million dollars in it.
Does anyone have any better ideas?
