Time. Time management, to be more precise. Time management is about prioritizing what is and isn’t important to you—what has to be done right now versus what can wait a bit.
Look at your to-do list (if you even bother to make one). Those things you continually push back? Unimportant, unless you’re not doing them for some reason.
What’s important to you? What are you doing? What aren’t you doing? Why?
Answer those and you’ll get a much better sense of where your time is going.
