Try to stop one day and watch how people walk.
Or observe how you walk.
If you want to increase your self-confidence to 200% or 300%, walk faster.
Because remarkable people have remarkable walk: they walk faster than the average. Their footsteps command power.
When you walk faster, you command an urgency to accomplish something.
When you walk faster, it forces your mind to think more efficiently and think with purpose.
Try it with this: chin up, stand up straight and walk with a great purpose to win.
