Agreed - in addition to this, I recommend having multiple devices. Create the first wallet - reset and restore. Then restore to a different hardware device - perhaps from a different manufacturer. Most of my setups are pairs of devices and wallets are pairs of pairs across to device types. ColdCard has a cloning feature which works perfectly. You can also test without sending transactions by just validating the wallet fingerprint or verifying the addresses it generates. They will be identical. Use a password (13th or 25th word). Store your seed on a physically durable material (like stainless steel). Store this separately from your password and preferably have copies and devices in multiple geographic locations. 

 this is the way..and this:
