What you actually pay for something is at least twice the listed price because of the energy， time， money needed to set it up， learn， maintain， repair， and dispose of at the end. Not all prices appear on labels. Actual costs are 2x listed prices.

完美不在于无可增添，而在于无可删减。

The only limit to our realization of tomorrow will be our doubts of today.

I’ve never believed in limits.

如果你想得到一切，就放下一切。
