How do I Make my Crypto Wallet safe?

As a cryptocurrency investor, I'm always concerned about the safety of my digital assets. Could you elaborate on some best practices to ensure the security of my crypto wallet? I've heard about using strong passwords and two-factor authentication, but are there any other measures I should take? Additionally, what are the risks associated with using public Wi-Fi or shared computers for accessing my wallet? Lastly, how can I recognize and avoid phishing attempts that aim to steal my wallet credentials? I'd appreciate any insights you have on these crucial security concerns.
