Minimalism + Bitcoin = happiness
I have been living this lifestyle for about 4 years. Everything I own can fit in a carry-on and a backpack (other than a box of childhood stuff at my mother's house). My expenses are about 10% of my monthly income having downsized to a small 35 sqm apartment. I bought a cheap/reliable car, paid in cash (my criteria was something that would last 2 years, good gas mileage and I wouldn't mind walking away from).
By doing this I can focus on the things in life that truly make me happy, last year I traveled to one new country a month. I don't worry about money like I used to. I will probably be able to quit my job in the next few years and do something I enjoy instead of just working for the money. And it has allowed me to accumulate bitcoins. Continuing this lifestyle will allow me to see the world and be independent/free instead of having to spend my life protecting my stuff.
Bitcoin does a lot to help with this lifestyle as I would not be able to be as mobile with gold, moving place to place carrying large amounts of gold across borders while I can carry my private key easily anywhere. I can always find a localbitcoins seller in whatever country I go to to get local currency.
