The Biggest Failure

i've spent almost hundred and 50 thousand dollars of my own savings building usebis. And this is only making about five thousand dollars inan annual revenue, not monthly. But as i mentioned before, i think my mistake was, in the beginning, underestimating uncertainty. I invested too much. The more i went to olin, the more i felt like a need to invest. However, there were other small things that i would d notesly. They weren't big failures, but there were things that didn't work as i expected.
