Try it on something that you're not relying on for your daily activities. It takes some time to learn and you'll make mistakes. But it's a great exercise for learning and as a hobby.

A side note. Tablets are good if you like to handwrite or take notes on slides or documents. If that's your plan, some software like xournal++ is probably the best, instead of LibreOffice. Otherwise, if you plan to still mostly if not only write via keyboard, consider sticking to a normal laptop. They are often cheaper and you'll write way faster than you can with a tablet.
