坚持成就非凡，复利方有大利。
伟大都是熬出来的，都是复利的积累。
在这个复利积累的过程中，好的方法不仅在积累的动作本身，更在积累的可持续性上。
甚至来说，可持续性才是关键，如果可持续，则什么方法都有效，如果不可持续，则什么方法都无效。
所以，可持续是前提，方法本身的优化只是改进，如果不能持续，则再好的方法也无济于事。
所以，做任何事情前，请先考虑它的可持续性，请先研究和确定如何实现可持续，否则，宁可不要开始。
Persevering in extraordinary achievements, the compound interest has a great benefit.
Greatness is the result of endure and the accumulation of compound interest.
In this process of compound interest accumulation, good methods are not only in the action of accumulation, but also in the sustainability of accumulation.
Even more, sustainability is the key. If it's sustainable, everything works. If it's not sustainable, nothing works.
Therefore, sustainability is the premise, the optimization of the method itself is only an improvement, if not sustainable, then no matter how good the method is useless. (then even the best method is of no help.)
So, before you do anything, think about its sustainability, study and determine how to achieve sustainability, otherwise, it's better not to start.
