I went through a sleepless night and started writing a blog because I had been too tired to stay in a bed. Yesterday, I wrote about "How to Use Saturday", so I must write something about Sunday now.
I use Sunday as the first day of a week. I prepare for a new week as a professional worker and start from something related to my personal life. A main preparation is to decide the goals and plans of a week. This action affects my brain to separate a week that ended until Saturday and a coming week that just begins.
I also do personal things to start a week to tell my heart and soul that time belongs to my personal life, not my professional career only. This is one of the most important rituals to realize my life as a personal belonging. This action also affects me to refresh my mind to let myself ready for a new week!
