“Lay hold of to-day's task, and you will not need to depend so much upon to-morrow's.”

Letter 1 again: same letter, same morning as the line about postponing. Gummere keeps the hyphens in to-day and to-morrow, and so do I.

This is the most practical sentence in the first letter, and it is the reason 🔹 Plan tomorrow's first task is one line on a card and not a list. The card is not a promise about tomorrow. It is today's last task: deciding, while I still remember the day, where the next one starts.
