If you work with your hands and your back, avoiding a heavy lift is totally understandable.
For many of us, though, we work with time or with trust.
If someone asks you to endorse their new project, “it’ll only take a minute,” they’re offering to save you time, but at the risk of the trust you’ve built. That’s not a light lift, it’s a huge risk.
If someone says, “please forward this to everyone in your address book, here’s a simple script to do it automatically,” that is indeed a heavy lift.
Just because it’s fast doesn’t mean it’s worth doing.
