Faster is more productive because it is a multiplier on tasks you spend a lot of time doing (thinking, writing, typing, debugging).
Being faster takes practice and most people don’t try to improve.
The way to be efficient for many problems is to be smarter. Counter intuitively, being faster helps you learn faster and have “better thoughts”.
Read Some reasons to work on productivity and velocity From Dan Luu.
- Speed is undervalued explains how product value changes with speed (time really).
- You can invert everything Dan says with inefficiency—slowness begets more slowness by becoming a habit.
- Surprise plus memory equals learning and being surprised more often (iterating quickly on different solutions) helps you learn more.
- Learning fringe programming languages makes you faster because you see more ways to solve a problem which are often transferable.
