If you want to be promoted up the ranks at work, you have to do more than a good job. You also have to be good management material. So, here’s how to become a better boss, whether you’re a boss-wannabe, or you’re already a supervisor, or a CEO.

First: Turn your to-do list into an “if-then” list. That means, stop writing down just the result you want like, “Make more sales calls.” The problem with to-do lists is they don’t tell you how you can accomplish something, or when. But an “If-Then” list does.  For example, “If it’s 3 pm, then I’ll stop whatever I’m doing and make 3 calls.” That makes you accountable to yourself on a daily basis. And you’ll be mentally primed to make those calls at 3 pm every day.

Another way to become a better boss: Do your hardest tasks first and often. It’s tempting to put off the things you don’t like to do – or what you’re not good at.  But managers have to repeatedly get outside their comfort zone if they want to improve their skills and grow. Think of yourself like a bodybuilder. You can’t just concentrate on strengthening your quads.  You have to work on your whole body, and do even the exercises you hate – to win the title.

Finally: If you want to rise through the ranks, implement a tactic a lot of corporations are trying: Never click “reply all.” Companies are beginning to realize just how much time these emails can waste. Not to mention it also raises the risk of accidentally sending something confidential or embarrassing to the entire company! So make an executive decision – or suggest to your boss – that the IT department eliminate the “reply all” option on company email. That’s what they’ve done at the Nielsen Corporation – which has 35,000 employees. Or you can install a free add-on to your Outlook mail called “No Reply All” which keeps anyone who gets an email from you from hitting reply all – or forwarding one of your emails.
