Knowing how to manage time is essential for your personal effectiveness. While there are many approaches to time management, here I’d like to focus on just one key mindset that I believe you should have: an investor’s mindset. Many people invest in financial instruments. I do, and most likely you do too. It’s common to think like an investor when it comes to money. But that’s not the case with time. I believe, however, that the principle of investing is equally applicable to time. Time is like money. You can invest it and reap rewards in the future. You can also spend it carelessly and go “broke.” What makes the difference is the way you use your time. It can make or break your life. The fact is that your time is a limited resource that’s even more limited than money. You can increase your savings so that you have more money to invest. But no matter what you do, you can only have 24 hours a day. So it’s important that you use your time wisely.
