The clock is running. Make the most of life today. To realize the value of ONE YEAR, ask a student who failed a grade. To realize the value of ONE WEEK, ask the editor of a weekly newspaper. To realize the value of ONE HOUR, ask the lovers who are waiting to meet.
Yesterday is history.
Tomorrow is mystery. Today is a gift. Listen and follow that inner voice for it is wisdom and knows what is best for you. Set gradual steps which you know are possible to achieve. Don't close doors on efforts before you have got them open.
