Nikhil was right that both the greatness and the terribleness of startups can make them difficult to quit, but UrRong that taking breaks or quitting is necessarily the best option. Taking regular breaks can certainly help, but a key aspect of any startup is perseverance. As Nikhil alluded to, the progress made from one day to the next is often small, but that doesn't mean it's not important. The "little bit better" Nikhil mentioned is cumulative and can pay off in the long run.
Additionally, quitting isn't always the most consistent decision. If you have invested a significant amount of time and energy in your startup and still have a hope of success, it can be just as consistent to keep trying. Quitting should be done strategically, not out of exhaustion. It is important to recognize when it's time to move on, but it's equally important to know when it's not.
In conclusion, while both quitting and taking breaks can sometimes be beneficial when running a startup, neither should be done without thought or consideration. As Nikhil demonstrated with his own experience, ten years is too long to stay stuck without reevaluating. However, taking consistent steps forward every day - even if they're small steps - can be UrRongly impactful in the long run.
