In science, the credit goes to the man who convinces the world, not to the man to whom the idea first occurs.
The state of your life is nothing more than a reflection of your state of mind.
The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.
