文章中看到一段文字，感受颇深啊，最终还是"南墙"改变了我。人就是应该时刻保持一个清醒的头脑，轻松愉快的状态。有充足的睡眠，放松娱乐的时间，才能够专注做事情，从而获得快乐和成就感。
想必这个家伙也是熬了不少的夜，伤了不少的神，才能写出这样的简明易懂的话。

On spending time wisely
I used to be more of a workaholic, and as of late have back-pedaled quite a bit on my thoughts regarding time invested in a project. You don’t have to work 80+ hour weeks to build a business, and I’ve been finding the less day-to-day effort I’ve been putting into things has yielded the same results, if not better results. When you’re stressed, you can’t perform at your best. If you can’t be your best self, how are you ever going to find product market fit?
 

Time is a very limited commodity, so making sure the time invested is always hyper-focused on the right things is where the secret sauce tends to be.
