About David Gleghorn

Founder of Success Is Mental.
Creator of the ULTRA YOU Method.

You Must Have Your Mental Plan First.

Everything begins in the mind. Before tactics, before training, before strategy - if you don’t have your mental plan in place, you’ll never reach your full potential. That’s the philosophy behind Success Is Mental, and it’s the foundation of everything I teach.


Who I Am

Hi, I’m David Gleghorn - founder of Success Is Mental, Becoming the Ultra You, and father of three amazing children (Shania, Kelsey & Harley), and a proud North Easterner with a lifelong passion for sport and human performance.

For over 20 years I’ve worked at the intersection of sport, business, and personal transformation. I’ve coached:

  • Teams to victory at Wembley.
  • An English Champions League manager on mental performance.
  • World Champion athletes across combat and endurance sports.
  • Blue-Chip leaders and sales teams to smash expectations in high-pressure corporate environments.
  • And I was invited to Oxford University to speak on mindset and mental performance.

Why I Do This Work

My journey into this field started with fear. A crippling fear of public speaking. At college I couldn’t deliver two minutes of feedback to three people without freezing.


Fast forward - I now speak to hundreds around the world. I’ve trained leaders, inspired athletes, and helped professionals unlock breakthroughs they never thought possible.


And I don’t just talk about it - I walk it. In 2023, at 53 years old, with no long-distance running background, I trained for just 15 weeks and ran 100km in a single day. Not to prove I was special - but to prove that with the right mindset, strategy, and system, extraordinary things are possible.

What This Means for You

Wherever you are right now - flying high and still hungry for more, or stuck in doubt, burnout, or fear - there’s always another level.

Sometimes it’s about quieting the noisy inner critic. Sometimes it’s about accessing the calm, certain voice inside you that whispers: ‘Maybe I could.’


My job is to help you listen to that voice - and then act on it.

  1. 1
    Clarity – Discover what you truly want and what’s been holding you back.
  2. 2
    Action – Get accountable and start moving fast.
  3. 3
    Momentum – Use proven strategies and structures to accelerate progress.

  3. 6

Breakthrough Stories

World Champion Breakthrough

"I attribute me dominating my weight class around the world in 2012, 2013, and 2014 to how Dave taught me to simplify issues and maximise my potential. Without sounding egotistical there isn’t a tournament in the world I didn’t win in my division."

Ross Gladwin - World Champion Kickboxer

Wembley Winning Breakthrough

“David came and delivered a talk to the team on the subject of Mindset ahead of our Wembley Final against Hereford FC. We won 4-1 and became FA Vase Champions. I would definitely recommend David to any sporting club, individual or business who is looking for ways to get the edge over competition, but more importantly to bring the best out in themselves."

Nick Gray -Manager of Morpeth Town FC, FA Vase Champions 2016
