Are you getting things done that you need to each day, or do you have so many distractions that you leave much unfinished?
If outside influences easily distract you from your work, or if you have a tendency to let your mind wander, remind yourself that God has given you dominion over the powers of your mind. You can close your mind to irrelevant things. You can concentrate easily at any time for as long as you need to complete a job.
Give your thought, interest, and attention wholeheartedly to the task at hand, and focus your energies on what you desire to accomplish. This is the secret of successful achievement.
