Some people optimize their schedule instead of questioning what belongs on it.

Rearranging a schedule is more comfortable than examining it. New systems, better blocks, cleverer sequencing, all of it engages with the how and never with the whether, and the underlying question of what deserves to be there stays untouched. The optimisation becomes a way of not deciding.

Before improving how you handle your commitments, go through them once and ask which you would take on again today. Remove one. That does more than any rearrangement.
