Stephen Covey's The 7 Habits of Highly Effective People: Powerful Lessons in Personal Change is a classic for both business and personal impact.
Here are the habits at-a-glance.
Be Proactive
This involves an understanding that we are our own people, accountable for our responses to external circumstances and able to initiate action ourselves.
Begin with the end in mind
Know where you want to go. Visualize what your future looks like. Begin acting in the way that your future self would act. Avoid activities (and relationships) which are not on that path to your future. This habit builds upon the first. Think. Then act. Demonstrate self-control.
Put first things first
Covey breaks things into four quadrants using the labels Important/Non-Important and Urgent/Non Urgent.
Quadrant 1
The Important and Urgent get deadlines and or they get addressed right away. Envision a fire - we address it right away.
Quadrant 2
The Important and the Non Urgent are scheduled and given the time and attention they deserve. This is the place where real, lasting progress takes place in our lives and in our organizations. It isn't glamorous and it takes discipline to not let these items get "rescheduled" or "postponed".
Quadrant 3
The Non Important and Urgent tasks should be delegated to the right person for the job. Here is an important question to ask, "Are you in someone else's seat, doing someone else's job?"
Quadrant 4
The Non Important and Non Urgent should not be part of your regular diet of activities. Doom-scrolling on the internet -- that's a distraction, leave that for your competition. Here's is a bit of a trick question, what about catching a game or movie with a good friend? Done well, that's actual Quadrant 2. Friendships and head-space matter. Learn to tell the difference.
Aim for Win-Win
Everyone wants to "win" but that does not have to come at the expense of a counter-party. In fact, a healthy marketplace relies upon win-win interactions. A one-sided win at the expense of another is unhealthy and either short-term or abusive. View every relationship through the idea that the next transaction is simply the first of a many to come in the future.
Seek first to understand, then to be understood
Practice empathy. Understand not only what someone is saying but seek to understand why they are saying it. Scripture says it this way in James 1:19, "My dear brothers and sisters, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry." These are words to live by. Simple. Not easy.
Teamwork
While Covey's habits start with control of self and independent thinking, really substantial accomplishment almost always requires the cooperation and mutual benefit of others. Learn to work together. This is mroe than "get help". Many things can only be accomplished, "together".
Sharpen the saw
Our learning and skill mastery is never complete. We always have further to go than we have already traveled.
