Many of our problems in life may be caused by not putting first things first. We often put off the important stuff that we don't feel like doing wasting time on the trivial. That leads to stress, and even anxiety.
From a Christian perspective, first things first means putting God first. Do you start your day with God? Starting the day with prayer, a Bible reading or devotional is a great place to start. Making time to be still before God and rest in Him. And keeping God present in your thoughts and actions all day.
First things first also means taking care of ourselves. We tend to put ourselves last, meeting everyone else's needs first. But if you are exhausted and burnt out, you can't help anyone. Take time to exercise and eat right. If you are an introvert, make quiet time for yourself. If you are an extrovert, make time to get out with friends. These things will have energize and renew you, allowing you to meet the needs of those you care for as well.
What are you doing today to put first things first?
Matthew 6:31-34 -- So do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' For the pagans run after all these things, and your heavenly Father knows that you need them. But seek first his kingdom and his righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
