I started with pencil too and upgraded to pen which is my favourite median. We all gat to start somewhere no matter how poor we are. We can still get better in the process if we persevere.
Though I do pencil work if requested, I don't like while drawing and I stop on the way to sharpen my pencil or use eraser. I prefer flowing with pen cause it makes me to be more careful and focused.
You can give it a try!
One day I will most likely but that day is still far away :)
