"Start where it's easier and most enjoyable", because if you like it, you will want do it again!
And if there is something mindfulness meditation is great for, it is the variety of practices:
1. Follow your breath - in any position you prefer, while sat on the floor, lying down on your bed, on during a walk in the park. "Breathing in, I feel my body. Breathing out, I smile."
2. Scan your body from head to toes - focus for a few seconds on each part of your body and the sensations (heat, pressure, clothing, vibrations...)
3. Watch your thoughts and emotions - Pause and ask yourself "How am I feeling right now?" and "What is the story playing in my head?"... or challenge your thoughts "Is that true?" and "Am I sure?"
