"People with goals succeed because they know where they are going, its that simple." Earl Nightingale.You need to know what it is you want the end result to be before you can start to create habits to get you there. A good goal has 3 components. It should be be short, specific and scheduled.
Short. Good goals are short because they are easy to remember and they are easy to follow. For example the goal of "Walk 10,000 steps a day" is the same as "Walk 4 miles every 24 hours at a pace of 3 miles per hour." The first one is far easier to remember.
Specific. You need to know exactly what you are aiming for. "I want to lose weight" is vague and you won't know when or if you have met the goal. "I want to lose 15 pounds" is much better because you can weigh yourself on a regular basis and see when you have met the goal.
Scheduled. Lastly, your goal needs a deadline. Knowing you have to meet it by a certain date gives you a sense of urgency and is an antidote to procrastination.
Once you have set your goal, write it down and post it somewhere you can see it every day.
