Inertia while important in physics, isn’t especially helpful when one wants to start a new career after, say 15-20 years or more doing the same thing. Commonly referred to as Newton’s first law, the concept of inertia says, “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.”
When I worked in Silicon Valley, pre-kids, Monday morning had a completely different context for me. It would set in at about four o’clock Sunday afternoon that Monday morning would soon be upon me. I needed to “shift” modes internally to put on my “kick ass and take names” hat, ditch self-care and relaxation that I tried to embody on the weekends, and get back to work. Most people who work full-time Monday through Friday jobs don’t have the luxury of taking the beginning of the week – the Monday morning – a little easier.
