The biggest changes in my life caused by bitcoin maybe is being patient and at the same time value the things that i am doing for my future like trying to save some of my earnings from bitcoin and buying only the important things needed for my daily life.
Just like you, the way on how I spend money was very different compared before. Now I think twice or even thrice if I should buy that thing because I only wanted them. And I am proud to say that now I have savings thanks to bitcoin.
