There's something in this picture. Some people knows how to carry themselves to exult that cool vibe that make us have to look twice. Learning how to walk the right way is an important step of fleshing out your inner power.
Walk with your head held high, your back straight (not slouched) and your feet strong and stable. Take decisive stride with toes pointing straight forward. A good posture can give you boost up a lot of confidence.
Some people walk with such nonchalance and without care about how people perceive them. It's not necessarily a bad thing, but it's not a great thing either.
