When you catch a glimpse of your potential, that's when passion is born.
Never make a promise without a plan.
No person ever ended his eyesight by looking on the bright side.
Failure doesn't mean you are a failure... it just means you haven't succeeded yet. Failure is a detour, not a dead-end street.
Obviously, there is little you can learn from doing nothing.
Have an attitude of gratidude and you will have more to be grateful for; have a complaining spirit and you will attract more to complain about.
