To get what you want in the decision making process you need to clarify what you want and what is most important to you.
1) Get crystal clear about what is most important to you in your life. This may be your family, partner, health, wealth or a combination of things. It is important to write these things down, too. Writing it down will stimulate other areas in your brain, and that will make the process more powerful.
2) Once you have written down what is important to you, clarify what you want and write it down. Write down, in specific terms, what is important to you and what you want. When you have written this down, look back at your list of things that are most important to you. Does what you want match with what is most important to you in life? Example: If you value being a rock star but your goal is to get a promotion at your job that prevents you from playing gigs as a rock star, then you have created an inner conflict. This is more common than one would think.
3) Make sure that what you want is based on what is most important to you in life. Write down specific goals based on what is most important to you.
4) Make a plan for how you can achieve each of the specific goals.
5) Each night, make a list of actions that you can carry out the next day to reach your goals.
After doing these five steps you will have a crystal clear idea if what you need to do. Now you need to do them. Everything you do either takes you closer or further from what you want.
You may want to lose weight, but eating five pounds of onion rings at lunch is not going to get you there. Your health may be the most important thing to you, but if you decide to go to happy hour instead of working-out you won't be improving your health.
These actions are based on instant gratification. To get what you want takes focus and consistency over time. If you were in the middle of a field with a shovel, and if you knew that you only needed to dig 10 feet into the ground to hit solid gold, you wouldn't start mowing the lawn. Yet people do this all the time in life by taking action toward things that are trivial compared to what they really desire.
Take TV as an example. Chances are, sitting around watching TV isn't going to take you closer to your goal. When your in the decision making process make decisions, base them on this question: "Is this helping me get closer to what I want?" Only answer this with a yes or no. Your answer will help you become more aware of your actions and help you make better decisions. Doing this will also keep you motivated because you'll begin to take more action that directs you toward what you really want. You will see the direct results of your actions.
