Believe in what you are capable of. 

The body achieves what the mind believes. So if you continually tell yourself that you can't or you will never be able to, the body will act accordingly. Start believing in your capabilities. You are amazing, and are meant to do amazing things, it's time that you believe that. Affirm yourself with this and don't worry about anything or anyone else. 

Activate your mind and body to start. 

The law of inertia is a powerful thing - ...A body is at rest ... will remain at rest ... unless it is acted upon by a force. A body in motion... will remain in motion... unless it is acted upon by a force. So, stop waiting for perfect. Just start. Activate your senses, activate your feet, and most importantly activate your mind to control the motions you are about to begin and continue on. 

See where, what, and who you want to be.

Continue to reinforce your goals with yourself as silly as that may sound. Hang pictures up of your goal, write them down in your weekly plan of why, and visualize yourself achieving them day in and day out until they come into fruition. This will continue to keep you consistently working towards them as well as make decisions that get you closer to achieving the goal. 

Know what triggers you to optimize results. 

We are all different in our own ways; what makes us perform well, what makes us unable to move and so much more. Uncovering what triggers those positive and negative reactions is key controlling your response, behavior, and ultimately your growth towards who you want to be.
