When you wake up in the morning and ask "What should I do today?", then surely you will have an action plan for the day. Make sure only to do one thing, once a day. One day you felt so good and do so many things, but the next time if you just chuck everything out, of course you will get stressed and even pass that on to the people around you. Stress can be contagious.
If only you knew how important and scary "doing one thing, once a day" is. A literary critic wrote hundreds of volumes of literary work. There is no one who has written that many works. Reading others' works and criticizing them is never an easy job. Many asked him how he could write so many books. He said he set a schedule to write just twenty pages a day. More than that, he catches an illness; less than that he catches an illness. More than that, he breaks his rhythm and gets sick; less than that, he gets sick because of the stress of "Tomorrow, I have to write even more" in order to meet his target. If you write twenty pages of a manuscript everyday, how many pages is that per month? Six hundred, right? In two months, 1,200 pages. For that amount, that is one volume already. In a year, that is six volumes. It may look like simple work, but from his steady effort, books are published and he has achievement.
There is a whole range of writers. Today one feels he can write well, feels active and writes one hundred pages, but tomorrow his shoulders hurt and his eyes are sore so he doesn't write at all and rests for a few days. That should not be done. If you just work continuously, you can reach a thorough achievement. In addition to working for a living, if you only do one thing, once a day, in one month that is thirty things you can solve. If you can spend your day like this, you can work joyfully without stress. Because you usually do a bunch of things at a time, naturally you get stressed out.
