What top founders protect on their calendar (it isn't the morning)

Morning routines get a lot of attention. The time of day matters far less than one thing: a long block where nobody can reach you.

Why long blocks win

Hard work (writing, designing, planning, selling to a difficult customer) takes 20–30 minutes just to get into. A day broken into 30-minute pieces never gets there.

How to build your block

1. Pick two or three blocks of 2–3 hours per week. Put them on your calendar like meetings.
2. Decide the task the night before. Starting the block by choosing what to do wastes it.
3. Remove the exits. Phone in another room, notifications off, one browser tab.
4. End with a note. Write the next step so tomorrow's block starts fast.

What to protect it from

Mostly from yourself: email, "quick" messages and small tasks that feel urgent. Batch them into one short window after the block.

Try it for four weeks and compare what you finish.
