Time is your only finite resource and it’s being stolen from you. Constantly. Time theft can be subtle. It comes in the form of polite and reasonable requests, of email CCs and FYIs, of commitments and obligations. If not caught early, succumbing to time stealing could happen throughout your whole career. You won’t realise until you look back and realise you have nothing significant to show for your labour.
Clearing your calendar of non-essentials is crucial to you doing the things you were put here to do. I don’t mean sending emails and passing time in between meetings. I mean the needle-moving actions that will get you from where you are now to where you want to be.
