Step One: Why are you unmotivated?
Clear you head. Sometimes you are just overwhelmed and you lose sight of your goals. So, do some relaxing activities like yoga, meditation, or even go for a walk or run in the park. Once your mind is calmed down you can more easily focus on your goals.
Step Two: What are you aiming for?
Remind yourself of what you are striving for; whether it be a long term career goal, or health goal or a short term goal like writing a paper or running errands. Now that your head is free of distraction, you need to reinforce your aspirations.
Step Three: Why do you want it?
Do not forget why you are pursuing these goals in the first place. Remembering why you were so passionate or driven to succeed in these tasks in the beginning will really revive your enthusiasm.
Step Four: How are you going to accomplish it?
Get organized. Create checkpoints for yourself so that you stay on task and can visualize your progress. Not to mention even reaching small goals gives you a sense of achievement that helps boost your motivation to reach higher.
Step Five: What are you waiting for?
Get up and get going! The hardest part is getting started. Once you start it is much easier to keep your momentum up. So do not waste any more time sulking, one burst of energy will make all the difference.
