Two things trip up most leaders’ attempts at managing their time. The first is the fact that the best systems and best intentions quickly run into dynamics in the real world: You’ll get interrupted, there will be an unforeseen obstacle or crisis, you’ll go through motivation and energy ups and downs, and so much more. Translating your intentions into practice often fails through small compromises you feel you must make in your day to day activities. The second is that most principles in time management focus on how you spend your time, but that philosophy just puts you on a “hamster wheel” that doesn’t move you forward. It isn’t about how you SPEND your time, it’s about how you INVEST your time.
