If you want to live a happy, fulfilling life, tie yourself to meaningful goals, not just to people and things.
Never put off or give up on something that’s important to you… not because you still have tomorrow to start or try again, but because

“You may not have tomorrow at all.”

Life is shorter than it sometimes seems. Make today count.
Take just one small step a day. Approach the start of every day with one little goal and end the day with one little word.
