Sometimes drawing every day is difficult, sometimes you don't feel like drawing, sometimes there's no time and sometimes you don't feel comfortable even in your usual workplace.
Sometimes, and it is the one that happens to me more often, no ideas come, I do not know what to draw and I find it difficult to think of something that encourages me to trace with the pencil.
That is why I have used the pages that make you a recommendation to draw daily.

I start with an ugly sketch that only I understand xD
But these strange sketches and lines help me start with the strokes that will give me the final result.
