Some people struggle with being mindful when it’s in the form of meditation or sitting still. If this is the case for you, then you could try practising mindfulness more actively by doing something that gets you moving. For example, you could focus on your senses or the feelings in your body while walking in the bush or going for a swim.
The key is to find the right activity for you and then practise staying focused, noticing thoughts, and redirecting your attention to what you are doing in the present.
