To avoid the intimidation factor, skip the notebook. Use the back sides of printed pages. Use cheap scribbler-type notebooks, if you can buy them where you live. And play with a few pens. I prefer fountain pens, and you can buy some very good ones for under $20, perhaps under $10. If you get a reloadable fountain pen, then you can save on the waste of plastic cartridges, and buy bottles of ink, which is where the fun starts.

As to what you ought to write, maybe start by transcribing some of your favourite poems, song lyrics, quotations, etc. Don't wait until you have some "big thoughts" that are "worthy" of a fancy notebook. Your first step is to see if it feels lie fun to you.
