I have clarity and energy.

Clarity and energy are usually not in the room together. Morning brings sharp thinking and no drive. Evening brings restlessness and poor judgment. Two in the afternoon brings neither, plus a blinking cursor.

That isn't a character flaw, it's a scheduling problem. Most people spend their clearest ninety minutes on email, because email is what was already open.

Notice today when your thinking is genuinely crisp. Then guard that window next week — one thing that deserves it, moved into it, and everything else pushed out into the fog.
