In working for myself I feel such pressure to perform, to keep up with what others are doing, and to be working all the time.
My rhythm is working from about 7-1, then a break for lunch. Then I go home and do some errands or housework until late afternoon, when I will work on projects that require less thinking until about 9, when I'll read before bed at 10. As a single person I have a lot of flexibility in my schedule, which I really enjoy.
I need that break from work in the middle of the day to rest or exercise (ugh - just sometimes). It's great to get away from the pressure to work 8 or 9 hours straight - or more - I don't know how people survive long term working 80 hours a week. I did that for a while as a teacher and became depressed.
I just don't think very clearly in the afternoons, and although early evenings are ok, I do my best work in the morning. When I sit down and prioritize my tasks, working on the most important ones first instead of the easiest or the most fun, my week goes so much better.
Taking time to rest reminds me that God is in charge. If I never sleep, if I never rest, I will be sick. But I will also not be trusting him to provide for me. God created us to sleep. He rested from his work of creation. I have permission - freedom - to trust that he is providing for all my needs and to rest from my work of creating.
"For everything there is a season, and a time for every matter under heaven:
a time to be born, and a time to die; a time to plant, and a time to pluck up what is planted;
a time to kill, and a time to heal; a time to break down, and a time to build up;
a time to weep, and a time to laugh; a time to mourn, and a time to dance;
a time to cast away stones, and a time to gather stones together;" Ecclesiastes 3:1-5
Where can you find room to rest today?
Do something that isn't productive but that makes you happy. Take a walk. Do a handstand. Draw with crayons.
