I tried pencil at first but with ink I liked that I can’t erase and can’t shade by using pressure.
So every mistake has to be transformed into something agreeable.
It is very productive to think about drawing in a logical way, e.g. how can I achieve what I want to achieve in a part of my picture. What also helps is knowing that a perfect drawing is a photo and I don’t want to produce a photo. And I try drawing what I actually see, not what my mind abstracts and thinks the picture should look like.
