I would say just for fun if you havn't done it yet setup an Electrum wallet. It's not quite the same as Trezor but you'll get experience with writing down a seed phrase, then delete the wallet and try to recover it. Just do that to get comfortable. Once you get your Trezor there's a bunch of step by step youtube videos that will walk you through the process but I'd be happy to help if you have any questions.
