i think every founder suffers from same disease "the overoptimistic underestimating brain" i have never yet in my founder journey woken up and thought "oh wow that took less than I thought and was as easy as I thought" it's always: "we planned too much, we can do 1/10th maybe if we get lucky and really try" which is why focus is so important radical focus means you choose the 1/10th that actually matters so stay focused
