Become a procrastinator because procrastinators find other procrastinators and they will keep you busy all year long. Stragglers are still appearing and I have 10 years to do for one entity. Learn to save any 1040-X, 1065-X, etc for after the deadline.  Do all your CPE after the final deadline since it will be fresh in your mind in time for 2018 returns. Live in Texas because all C Corps, S Corps, limited partnerships, LLC's have Franchise Tax Reports due on November 15th. Payroll taxes go on all year long.  Since I have known most of my clients for over 30 years, I have a number of dinner and luncheon invitations in the next few weeks. The list is endless.
