We are what we repeatedly do. Excellence, then, is not an act, but a habit. ~Aristotle
This is one of so true it stays posted on my wall. When things are not working smoothly in my life I usually take a look at how that connects to my personal habits. Then, adjusting my personal habits accordingly fixes the issue, or at least improves the situation, the majority of the time.
For example, when I for whatever reason start putting off doing little chores at home, that procrastination builds and spreads, like a disease, to all the other parts of my life. Soon I am putting off big things and not staying on top of important things. Once I reverse this and address even the smallest of matters in a timely fashion (like finally washing those dishes, or replacing the batteries in the chirping smoke alarm) that energy also reverberates to the other sections of my life (staying on top of my work schedule, paying bills on time, etc.). Effective planning is a habit I am currently in the process of building (emphasis on effective).
So the message here is to make sure that what you do repeatedly, your habits, are serving you and facilitating the type of life you want to live. If they aren’t let them go, replace them with actions that do serve you, and watch how your life changes for the better. As Zig Ziglar says, self discipline is the key to excellence!
