Like locks and doors, secure and safe are not a binary state, it's a spectrum, where your purpose is to provide more hurdles of time, effort, discovery, consequences, etc to the attacker such that what they would want from you is not worth it. Nothing will leave you entirely secure (and conversely nothing will leave you entirely insecure. You can leave piles of cash on your front porch and it still depends on someone actually walking by to note there's something to steal). If you're a bank in a metropolis, you get a sophisticated vault. If you're a business you get an alarm system to protect your inventory. If you're a farmer and it's the less expensive farm equipment, you might not even lock the barn/shed. If you expect state level adversaries, you probably need state level resources, planning, and mitigations. If you're jane/joe schmoe citizen, don't give out your passwords or click on unknown binaries, and be wary of people asking you for SMS codes in IMs. Scale appropriately for the threat you think you'll face, and as much buffer as you think you can stomach.
