Some work days are best done in reverse.
Yes, I know that you are comfortable doing A, then B, then C.
But every now and then, Z comes along.
Z makes you uncomfortable. Z threatens what you know works. Z has to be dealt with now. Z changes the order of things.
Plan for Z. Learn to dance with Z. Tell Z, "I will still do C, then A, then B later. You cannot stop me."
Uncomfortable is when your best work will appear.
