While I would argue with or add to some of his advice, Stephen Covey, best known for his book 7 Habits of Highly Effective People, was a strong voice in the world of goal achievement and leadership. RIP, Mr. Covey.
What follows is from Wikipedia. It’s an outline of Covey’s 7 Habits of Highly Effective People, which has sold more than 25 million copies worldwide since its first publication in 1989.

Independence or Self-MasteryStephen_Covey_(author)_-_FMI_Show_Palestrante

The First Three Habits surround moving from dependence to independence (i.e., self mastery):

  • Habit 1: Be Proactive

Take initiative in life by realizing that your decisions (and how they align with life’s principles) are the primary determining factor for effectiveness in your life. Take responsibility for your choices and the subsequent consequences that follow.

  • Habit 2: Begin with the End in Mind

Self-discover and clarify your deeply important character values and life goals. Envision the ideal characteristics for each of your various roles and relationships in life.

  • Habit 3: Put First Things First

Prioritize, plan, and execute your week’s tasks based on importance rather than urgency. Evaluate whether your efforts exemplify your desired character values, propel you toward goals, and enrich the roles and relationships that were elaborated in Habit 2.

Interdependence

The next three have to do with Interdependence (i.e., working with others):

  • Habit 4: Think Win-Win

Genuinely strive for mutually beneficial solutions or agreements in your relationships. Value and respect people by understanding a “win” for all is ultimately a better long-term resolution than if only one person in the situation had gotten his way.

  • Habit 5: Seek First to Understand, Then to be Understood

Use empathic listening to be genuinely influenced by a person, which compels them to reciprocate the listening and take an open mind to being influenced by you. This creates an atmosphere of caring, respect, and positive problem solving.

  • Habit 6: Synergize

Combine the strengths of people through positive teamwork, so as to achieve goals no one person could have done alone. Get the best performance out of a group of people through encouraging meaningful contribution, and modeling inspirational and supportive leadership.

Self Renewal

The Last habit relates to self-rejuvenation:

  • Habit 7: Sharpen the Saw

Balance and renew your resources, energy, and health to create a sustainable, long-term, effective lifestyle. It primarily emphasizes on exercise for physical renewal, prayer (mediation, yoga, etc.) and good reading for mental renewal. It also mentions service to the society for spiritual renewal.
