Unsubscribe from emails
This one sounds easy but it actually makes a world of difference. The goal, inbox zero.
You know you get pesky emails from all sorts of companies. Start unsubscribing. Do it often. Start with your junk or spam folder. Identify and then eradicate those egregious offenders.
Manage your emails by searching by a specific brand or company name. This is a great way to mass delete all that junk mail you're never going to read.
Remember what I told you, unsubscribe often. Sometimes you still get junk even after clicking that tiny link at the bottom of those emails. Be persistent. It will pay off when you start seeing a lot less junk in your email. Trust me, you will start to feel a lot less stressed and a lot more in control of your digital life.
