What habits destroy a person’s future slowly?

What habits destroy a person’s future slowly? I’d say scrolling on the phone is a big one these days. I read a recent study that showed a dramatic drop in fertility rates after the arrival of smartphones in 2007. People just aren’t socializing or interacting anymore. They will lay on their couches on their phone for days on end. One strategy to help with this is to do a nothing alternative (which helps enormously with procrastination). People often think they did nothing on a given day. But they actually did do something: they were scrolling on their phone. If you give yourself the option of doing nothing but the important task, you’ll eventually realize that boredom is even worse than doing that task.
