We found it very difficult to save, especially in the early years when we were a lot more worried about where the next weeks groceries were coming from rather than saving anything. As I went from farming (a deficit) to corporate work (a surfeit) we became able to save, and the best way for us was to have it deducted before we ever saw it. I have participated in every possible retirement and savings vehicle my employer offered, and have tried to absolutely max them out, since we had to do so much catching up. So, as my income increased, we tried to not spend the increase, and save it, constantly increasing our contributions to various plans. As an example, we have saved EVERY bonus I have ever received in this manner. It has enabled me to FIRE (4 more months to go), although not really very early. I'll be 64 in January...
Carpe Diem, Vita Brevis
