Summary of Podcast #23 Transforming Mindsets: Cosi Naum's Guide to Authentic Living

In our latest podcast episode, Ann-Marie Antic spoke with Cosi Naum, a mindset coach and wellness champion. Cosi shared her journey from competing in bodybuilding to helping others break through their limiting beliefs. Her insights on mindset are inspiring and practical for anyone looking to make positive changes in their life.

Mindset is the Game Changer

One of the biggest lessons Cosi shared is that our mindset shapes our success. Often, the biggest obstacle is the negative voice in our own heads. Cosi encourages people to challenge their inner critic and replace negative thoughts with positive affirmations. By shifting our mindset, we can unlock our true potential.

Helping Women Reconnect with Their Authentic Selves

After a major life change, Cosi realised how important it is to understand what truly matters to you. She now helps women rediscover their values and passions, guiding them to live more authentic, fulfilling lives.

Practical Strategies to Overcome Limiting Beliefs

Cosi shared some powerful strategies to help you rewire your mindset:

  • Identify negative thought patterns – Recognise when self-doubt creeps in.
  • Challenge those thoughts – Ask yourself if they are really true.
  • Replace negativity with affirmations – Focus on thoughts that support your growth.
  • Practice gratitude and mindfulness – Stay present and appreciate your journey.

If you’ve ever felt stuck or held back by self-doubt, this episode is packed with practical advice to help you move forward. Cosi’s story proves that with the right mindset, transformation is possible.

Cosi’s Practical Tips

As a bonus, I asked Cosi to share some tools and practical advice. Here are actionable strategies you can start using today:


Practical steps to overcome self-doubt:
  1. Start to notice and label your unhelpful thoughts. Are they stemming from your inner critic?
  2. Write down the limiting belief holding you back e.g. “things like this don’t happen to me” 
  3. Find evidence that disproves it.
  4. If you find evidence that proves it- ask yourself “how can I use my existing strengths, supports around me to help me overcome this?”, “what is this teaching me?”, “in what way is this challenge providing me an opportunity to growth?”
  5. Find a more balanced reframe or affirmative thought e.g. “ I could be the first” that you believe and positively influences how you feel- this is more powerful than the limiting belief because it has taken more conscious energy to create it.
  6. Take one small, brave action to challenge it daily—action is the antidote to doubt.


How to overcome Fear of failure. 

Overcome it by taking imperfect action—momentum builds clarity and confidence. Remind yourself:

  • You’re improving every day.
  • Every challenge is preparing you for growth.
  • Hard things are happening to help you constantly evolve into your potential.


Breaking free from ‘shoulds’?
  • Get clear on your values and what genuinely excites you.
  • Replace “should” with “choose” and notice the shift in your mindset.
  • Reflect on where the “shoulds” come from. If it’s societal pressure, ask yourself why it matters. If it’s your inner critic, consider whether it’s a fair expectation.
  • Treat yourself as you would your best friend. How would you respond to a friend that was doubting themselves or putting unfair pressure on themselves? Likely, with understanding and encouragement—not judgment.
  • Practice self-compassion I.e. treating yourself with loving kindness.


Recommended Daily practices for alignment?
  • Gratitude journaling: Focus on what you’re thankful for and reflect on why this was meaningful.
  • Meditation: Quiet the mind and reconnect e.g. grounding with your five senses.
  • Visualisation: Imagine your goals as reality and how it would feel if you achieved this outcome.
  • Movement: Energise your body and mind.
  • Self-care: Carve out time to reflect, recharge, and nurture yourself.
