„Я предполагаю, что если единственный инструмент, который вы имеете — молоток, то заманчиво рассматривать всё как гвозди.“

If you start wielding a hammer, then all your problems look like nails. And maybe they’re not. Maybe it's more subtle than that. And so your toolkit has to be able to morph into what is necessary for what it is that you confront at that moment.
Вариант: Когда берёшь в руки молоток, все проблемы становятся похожи на гвозди. А может, они не гвозди. Может, всё тоньше. Поэтому инструментарию должно хватать гибкости превращаться в то, что нужно для текущей задачи.

To regard human beings as tools — as instruments — for the use of other human beings is not only unscientific but it is repugnant, stupid and short sighted. Tools are made by man but have not the autonomy of their maker — they have not man's time-binding capacity for initiation, for self-direction, and self-improvement.

I approach playing acoustic guitar more of as a percussive instrument. It's fragile. I don't have a lot of finesse when it comes to my guitar playing.
