An example of keeping things simple is that instead of storing your Bitcoin in a multi signature wallet that you do not understand how it works or have no experience in setting up, store your Bitcoin in a soft like Electrum wallet where the process of setting up is pretty straight forward.
Learn then practice and to avoid loss by practical mistakes by lack of knowledge and experience, make your first practice to test your knowledge with Bitcoin testnet. If you make mistakes with Bitcoin testnet, you don't lose any money.
Create your wallet, backup and use your backup to recover your wallet.
If you want to use that (like a multisig) wallet to store your coins, send a small amount to it and practice to sign a transaction from co-signers. If it works, you can send more bitcoin to it as you already know how to broadcast a transaction from a multisig wallet.
Another example is using simpler and recommended ways to protect your seed phrase instead of some ways that has too much complexities and technicality to it any mistake can result in its loss forever.
Don't do complicated backup like splitting your seed to some parts. Because if you lose one part, you can not brute force it to have your full wallet seed. That causes you a loss of your bitcoin because you can not recover your wallet.
