We all probably did it but is it the right approach? In our opinion you really don't have to work 10-15h to do your job properly and become successful at what you do. There might be occasions when you have to stretch to meet a certain deadline or to deliver on your promise. Most of the time however, it's a matter of focus, time and energy management. You can really have a much better work-life balance if you change your bad habits and take control of your daily routine.
