Basically my biggest sacrifice is the present for the future. Sacrificed food where I can. For example instead of buying peanuts I buy bananas. Sacrificed the place where I live also, it has been now almost 10 years with not so much holidays, not going outside often, not buying clothes where I can (I wait for holes to really become big). I try to avoid also living in rich countries and favor poor countries. With currency arbitrage we can save quite a bit. So not going to the US to pay a $1000 rent for example hahaha.
