Nothing is showing up in your spoilers, just so you know. I'm not seeing any images.
That aside, I started off drawing with pencil. For years and years I did nothing but doodle with pencil. I drew on just about every piece of paper that sat in front of me. My school notebooks are full of doodles. I used pen and colored pencils rarely, but most of it was all just pencil and paper. Just a lot of stupid little things, like this:
Although I always wanted to draw well, I never really gave it a serious effort until I was about 19 or 20 years old. I then tried digital art for the first time, and made my first few digital drawings with the touchpad mouse on my laptop. I may have used a regular mouse once or twice, but I think the touchpad actually gave a little better control.
If I didn't want to do line art with a mouse, it would also sometimes be helpful to just scan pencil/pen line art, then clean up and color it digitally.
Over the next two years, I took art classes at college, got a tablet to make digital drawing easier, and have worked to improve my overall art skills. Drawing with a tablet definitely takes some getting used to, and there are some people who just don't like to use tablets, but I love my tablet. After getting used to it, I actually think I draw better with the tablet than I do with a pencil. I dunno why.
My first drawing tablet broke after a year (it was my fault, not the hardware's), and I'm now on my second one. This tablet has lasted almost three years now.
Not sure if any of that helps you, but there you go.
