Lots of ways, unfortunately. It can be quite a complex process if you have never done it before.

Provided your private key never touches your online device, and you don't sign a transaction without double checking it is correct (and therefore making sure it has not been altered or tampered with by any malware on your online device), then it is incredibly unlikely that any mistakes you make would result in loss of your coins. With that in mind, the most important thing to remember, as I said above, is to ensure you only ever enter you private key or seed phrase on to your airgapped computer, and you only enter an address or public key on to your online computer.

If something goes wrong or doesn't seem to work as you expect, then simply stop, look for the mistake, ask on here if needed, or even start from scratch. Just take your time with each step.
