Have you ever watched a young child doing arts and crafts? They are so peaceful and focused putting their "all" into their project. They don't worry about what others will think or say. Nor do they worry about what other things they need to accomplish that day. They are wiser than we give them credit for.
I am a very strong believer that everyone needs some sort of creative outlet in their lives. It gives your mind a chance to relax and just "be". The more hectic life gets the more you need your own "space" and time for yourself. Whether you create something of your own or share in the creativity of others (reading a book, watching movies, going to museums, etc.) you need to take time at least once a week to do so. When you have that downtime in your life, big problems you face at work or at home become easier to manage. You feel less overhwelmed. Stay-at-Home-Parents tend to do this less often than they should and many times feel harried by day to day life. One little hour a week can do wonders to your health and sanity! Whether you take it all at once or split it up really doesn't matter. Just find time for yourself! You are a much better person and are much more productive the rest of the time. You are no good to your family or boss if you don't.
