The elements that we do not compromise on daily. These are essential to our success. No different from brushing your teeth at least twice a day as part of your hygiene routine or getting eight hours of sleep. Do you have non-negotiables as part of your productivity regimen?
When we pay attention to what makes our days good, productive, and positive, we notice trends. If these practices and habits are not a part of our routine, ask yourself why. Conversely, if you know what works for you, look to embed them as part of your day. Similarly, the habits, practices, and people that drag you down take note too and eliminate those.
Observe, recognize, reflect and create your non-negotiables. You will be a better you for it and they are yours.
