可持续性不是一种选择，而是一种责任。
Sustainability isn't an option; it's a responsibility.
Separate the processes of creation from improving. You can’t write and edit， or sculpt and polish， or make and analyze at the same time. If you do， the editor stops the creator. While you invent， don’t select. While you sketch， don’t inspect. While you write the first draft， don’t reflect. At the start， the creator mind must be unleashed from judgement.
如果你不愿意学习，没人能帮你。如果你决心学习，没人能阻止你。
