Routines can also create unwanted distress or angst. Sometimes our routines can become so over complicated or suffocating that they drain the joy out of life. Our entire focus can become exclusively about our routines and color the way we see the world. If something messes up our routine it is then deemed 'bad' regardless of the situation.
This has happened to me in the past to me especially when it comes to working out and eating healthy. You can begin to focus on specific aspects of life, of trying not to cross certain lines that you fail to enjoy opportunities when they pop up. While I attempt to eat in a pretty simple way, if a friend asks me over for dinner, no longer do I say no just because I know what they may be cooking isn't the best possible meal for me. It's more important that I enjoy the time I get to spend with them rather than worrying about the calories I may consume.
I'm learning that I can simplify my routines so that flexibility is a positive rather than a hindrance to my goals. This brings a new level of joy that I had not yet experienced in the past. It seems like a good way to live.
