The First Thousand Days

Nobody tells you that the hardest part of founding a startup is not the product or the fundraising or the competition. It is the emotional rollercoaster. In a single day, you can go from 'this is going to change the world' to 'this is definitely going to fail' and back again three times.

The first thousand days are about survival. You will pivot your product, lose your first employee, discover that your market size estimate was optimistic by a factor of ten, and question your sanity approximately once per week. This is normal. This is the process.

What separates the startups that survive from those that do not is not a better product or more funding. It is the founder's ability to absorb uncertainty without breaking. Resilience is the only non-negotiable founder trait.
