The first level of freedom is to do whatever you want, to act on impulse, such as smoking, drinking, and scrolling through Twitter.

The second level of freedom is to do whatever you want, but to engage in long-term rewarding yet difficult activities, such as exercising, reading, studying, building a personal brand, and making money. However, this requires suppressing the first level of freedom; for example, if you're scrolling through Twitter every day, how can you focus on reading and studying?

The third level of freedom is a further expansion of the second level, because by engaging in more long-term endeavors, your range of choices expands. For example, you can live in a nice house, travel abroad, and choose better partners...

The final level of freedom is to break away from external standards of choice and attain spiritual freedom; even if you have to clean the sewage every day @zhangtian186556, you can still enjoy it and be happy. 😂
