The bare minimum you want to do is the following -

1. Setup nano or trezor -
   
   ledger nano S crash course:

   or
   
   trezor one wallet = ~54 USD

   Trezor Model T = ~164 USD

2. Record your 24 words on paper + record your passphrase on a separate paper you keep private and secure and separate from your hardware wallet and each other. You will both memorize your passphrase and pin + keep it in writing but not with your 24 word backup. Never store passphrase or mnemonic backup digitally.

3. Send a small test amount of BTC to your HW wallet receive address. You are going to send BTC to your hidden wallet with the passphrase.
   
   
4. Confirm you got the BTC, reset your HW wallet, recover it with 24 words + passphrase . Now you have trained yourself how to recover a wallet with backup and 100% confident you did everything right once you see the BTc again in your hidden wallet. Congrats, have a beer.
   
   
5. Send a small amount of BTC to your non hidden wallet(protected by pin) , and the rest to your hidden wallet(protected by passphrase). Done, have another beer.
   
   
6. You should seriously consider using a metal backup-

   Some foundational Principles of security
   
   
7. Never store your bitcoins in a web wallet or exchange . You own 0 bitcoins if you do not control your private keys.
   
   
8. Diversify your BTC storage either split between multiple wallets from small spending amounts in a smart phone for convenience to one or multiple hardware wallets. The more Bitcoin you have the more you should begin to consider using multiple hardware wallets and BIP39 paper wallets and or multisig HW wallets configuration –

9. Buy your hardware wallet directly from the producer or amazon site under the producers name. Verify the integrity of the hardware wallet if you are extra paranoid :

10. Never brag about your wealth to others
    
    
11. Never invest in any investment scheme or get greedy thinking you can quickly increase the amount of Bitcoin you have with daytrading
    
    
12. Consider more secure means of backing up your 12 or 24 BIP39 backups in case of floods or fire - https://cryptosteel.com/
    Or https://billfodl.com/products/the-one-and-only-billfodl
    or https://bitkee.com/ or https://cryptokeystack.com/

    Use steel , brass, or copper or other durable metals. Wood and aluminum are unacceptable.
    
    
13. Setup your hardware wallet , transfer a small amount of btc to it, wipe it clean , and restore it to give you confidence that the backup was done right and give you experience in the recovery process.
    
    
14. Keep your Mnemonic 12 or 24 word seed secret and private and show to no one. Never use premade 12-24 word backups , you create new keys and backups upon setup.
    
    
15. Lastly Never store your bitcoins in a web wallet or exchange . You own 0 bitcoins if you do not control your private keys.

Lasts you a lifetime:

Amazon-Link to Metal Stamping kit

Also notice, that all words in a BIP39 mnemonic are uniquely identifiable by their first 4 characters. So for a 12 word seed you only have to stamp 12 * 4 = 48 characters (not counting spaces).

You can buy your own engraver. Or dremel tool with engraver bit. But best (and cheapest) is the letter punch set, like this https://www.amazon.com/Vector-Number-Capital-Letter-Punch/dp/B01A1CTYG2/ref=sr_1_3?ie=UTF8&qid=1504064933&sr=8-3&keywords=letter+punch+set

Will take about half an hour to do 24 words. I've tried it on stainless steel plate (slightly more difficult) and on aluminium plate (much easier, because allu is softer). But alluminium has much lower melting point. Decisions, decisions :)))
