One time I heard the most incredible piece of advice regarding motivation and inspiration...
It went like this. "Imagine that you're the lead character in an action movie. What would that character do if he had your life today?"
Now this doesn't mean you should start doing stunts off high buildings and buying well-tailored clothes you can't afford.
It's a suggestion to watch the characteristics that action heroes display in movies. Notice how they always have character in abudance? They're a magnet to everyone else in the movie? Everyone is drawn to them.
They may exhibit grit, determination, elegance and number of other qualities that humans are naturally drawn to.
If you ask yourself what your favorite hero would do in each situation you face, you may just emerge with a new perspective on what you're capable of achieving.
