As Dweck explains, people usually have a mix of two mindsets, and that their mindset can change depending on the context or point in life.

First things first - without recognizing your way of thinking may need some tweaking, you're unlikely to achieve anything. But don't just stop there. Give yourself a chance to grow your Growth Mindset.

• Learn to spot when your thinking is slipping into Fixed Mindset, e.g.
  - 'I love the idea of joining this project, but I don't have all the skills they need and I'm probably too old to learn'
• Recognize your mindset is your choice, so choose right.
  - 'But this is just one way looking at it. On the other hand, they really appreciate my expertise and experience so far and believe I can do it'.
• Talk back to your Fixed Mindset voice, using Growth mindset logic to argue, e.g.
  - 'Actually, many people managed to learn new things, even at an older age. I'm not dumb, I could try.'
• Take Growth Mindset action.
  - 'How about I start learning about that digital marketing and see how I go?'
