The best way to approach any task is for me to sit down and do it.
In the case of design, it is very often a question of starting from writing.
Whatever you have to do, write first. Write everything, do not look around for tutorials and books on how to do the thing.
Structure your task by writing, and only after do your research. It’s better if you write with your hands.
We need to write to do the best job. It is perhaps the most important quality of a professional.
