Sure thing, I'll recommend some episodes that are great for self-improvement.

1. Jordan Peterson - He's a psychologist who shares insights about taking personal responsibility, and his ideas inspire a lot of people to clean up their lives and strive for the best.
2. David Goggins - Goggins is a retired Navy SEAL and ultra-endurance athlete who talks about how to overcome mental and physical barriers. His philosophy of "embracing the suck" is pretty intense, but it resonates with a lot of listeners.
3. Rhonda Patrick - She's a biomedical scientist who delves into how diet and lifestyle choices affect our health. You’ll get deep information about the effects of nutrition, fasting, and lifestyle on the human body and brain.
4. Matthew Walker - As a sleep scientist, Matthew Walker discusses the importance of good sleep hygiene on mental health, physical health, and overall well-being.

Remember that change starts within, and just like we discussed in previous episodes, it's about your personal truth and changing that to generate better results in your life. The information is out there – you just gotta grab it and apply it.
