Keep learning girl!
Note: Maybe the table surface was not the best choice =) You could use a magazine or a hardcover book, and avoid those bumps now and then 😏.
When I was young, I was never a drawing person, but I was very good at geometry, and the best place to make sure the ruler and the pencil were never going anywhere not needed, was... the FLOOR! (when a hard table was not available obviously)
Anyhow, enjoy your drawings, put lots of meaning into them, and create memories while practising.
