I start every morning by writing out my long term and short term goals along with daily action steps as to how I am going to get myself closer to reaching these goals. I write out the goals every day as an affirmation to myself that I will achieve them, in my mind I have already achieved them it is just a matter of them coming to fruition. I have no doubt in my mind that I will achieve them and that is because I can visualize myself having already achieved them. Writing down your goals EVERY SINGLE DAY makes you focus and remember what you are working towards in life, why you do what you do and it ultimately affects each choice you make. I highly recommend you do this even if it's just spending 5 minutes while you have your morning coffee. This 5 minutes will make your day so much more purposeful and productive - try it for a week and see.
There are 2 different types of goals:
OUTCOME GOALS - these are the main objectives that you hope to accomplish e.g. I want to lose 5% bodyfat in 6 weeks. You can't directly control the accomplishment of an outcome goal, it is the end result of actions you have taken to achieve that goal.
BEHVIOUR GOALS - these are the steps you have taken to accomplish your outcome goal. Using the same example as above some steps you might take would be to weight train 5 times a week for 6 weeks and to eat a certain number of calories everyday. You can directly control a behaviour goal, it is an action you choose to take (or not).
How should I set my goals?? S.M.A.R.T
SPECIFIC - they are specific actions you can take that will lead you in the direction of your purpose.
MEASURABLE - this allows you to judge your progress towards achieving them.
ACHIEVABLE - not so easy that they don't require effort, but not so hard that you regularly fail to reach them and become disheartened.
REALISTIC - they should fit into who you are as a person, what you stand for and what you are capable of.
TIMELY - a definitive timeframe and there should be markers along the way that you can measure whether you are progressing towards the goal.
