When I ask people what it takes to achieve greater things, one of the most common answers is that you need to be laser focused and single-minded in your dedication. You need to double down and block out anything that threatens to drain your energy or divide your attention. If you want to excel at your job, spend more time at work: get in early, go home late. Put your hobbies on the back burner … and definitely don’t take on a side hustle.
