It's really worthwhile to take notes on spontaneous thoughts or ideas.
Just as a blacksmith squeezes iron on an anvil, an idea can only be achieved in a physical pattern if it is well refined and transformed in a practical way. Notebooks can be compared to an anvil. For example, the tempering process is iron adjusted and it forms a specific piezo curve.
To build up ideas, we can use mind maps as an effective tool among proven methods because our brain cells are like networks they linked to each other, and ideas are also interconnected. Wherever you are, you can resume working on your ideas immediately by looking at the mind map of your mobile device.
