Drug-Augmented TMS Accelerates Change

Pairing accelerated TMS with D-cycloserine may amplify neuroplasticity and shorten treatment time.
Tim reports one-day TMS plus DCS produced durable benefit where prior sessions had not.

Use Ketosis Strategically

Consider intermittent ketosis or ketogenic cycles for potential neuroprotective and psychiatric benefits.
Weigh plausible upside against manageable downside and consult medical guidance for personal risk.

Choose What To Optimize First

Ask yourself what you're optimizing for before optimizing how to do it.
Prioritize a few high‑leverage goals instead of optimizing many unimportant tasks.

This episode is a bit different, and I am in the hot seat. Dan Harris (@danharris) interviewed me for his show, the 10% Happier with Dan Harris podcast, and I thought it was worth sharing here. Dan is a wonderful interviewer, and we got in the zone. He is also the bestselling author of 10% Happier and Meditation for Fidgety Skeptics: A 10% Happier How-To Book.
