Tough times never last, but tough people do.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Fall down seven times, stand up eight.

You cannot start the next chapter of your life if you keep re-reading the last one.

Success is the sum of small repeated efforts, day in and day out.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

The power of reflection is the most powerful skill you’ll learn.

The bad news is time flies, the good new is that you're the pilot.

Everything that happens was once a dream.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.
