Every person who has ever built anything real hit a point where stopping felt like the sensible option. The idea was not working. People were not responding. The money was running low. Doubt was very loud. The builders who made it through are not always the smartest or the most talented. They are the ones who did not stop. Persistence is not stubbornness — it is not ignoring evidence or refusing to change course. It is continuing to work on the problem even when the work is not returning results yet. The results come later. The work comes first, every day, whether it is working or not.
