Dedication or Insanity?

I have actually been thinking about some more specific goals since last time I mentioned it. I need some more time to think through what is actually realistic but in the mean time I've been reading a really excellent personal finance blog about a 26-year-old man in Stockholm whose aim is to become a millionaire before he's 30. Sadly for some, the blog is in Swedish so only very few of us can share his thoughts and crazy ideas but what made me fall completely for his blog is his obsession with saving money. Of course, he has investments and it's interesting to follow his ideas around this but what's even more interesting is every other month when he has a "stingy month". This means that he goes from saving a minimum of say SKR 6,500 a month to saving a minimum of SKR 10,000 or so a month (equivalent of about £500-£900). He does this by completely controlling any expenditure that is not absolutely necessary.

This guy, who calls himself "miljonaren" - the millionaire -has a maximum spend on food of about £1-2 per meal and doesn't buy anything, ANYTHING else but food. One month he writes his blog from a hotel room whilst on a business trip. Instead of going for dinner with his colleagues he lies to them to say he has friends in that particular city and then sneaks up to his room to eat beans, that he has brought from home, straight out of a can! Now, is that dedication or pure insanity?

I don't think that I could be as extreme as him in saving, nor do I particularly want to but his passion for what he does is really inspiring, and he is well on his way of reaching his goal so he must be doing something right!
