Place a high value upon your time; be more careful of not losing it than you would of losing your money. Do not let worthless recreations, idle talk, unprofitable company, or sleep rob you of your precious time. Be more careful to escape that person, action, or course of life that would rob you of your time than you would be to escape thieves and robbers.
~ Richard Baxter,
quoted in Home Educating Family magazine
Be very careful, then, how you live--not as unwise but as wise, making the most of every opportunity, because the days are evil.
~ Ephesians 5:15-16
