Starting a business is indeed a continuous process of finding holes and fixing them. Holding a hammer in hand, everything looks like a target. Sometimes I feel my product isn't good enough, and other times I think the team could be stronger.

However, this is destined to be the eternal sorrow and blessing of entrepreneurs. Although it's exhausting, you must learn to accept it calmly.

At 26, it’s gone in the blink of an eye. Looking back, it seems like everything has transformed completely, and the people around me have come and gone. The entrepreneurial journey that started at 24 may not necessarily have been better, but at least I might have experienced some of the losses that young Elon Musk didn't face when he launched Zip2, and perhaps even endured greater pressure than he did.

And then, his life truly entered a hellish phase, where desensitization and numbness became essential lessons for the desire to succeed and reach the finish line.
