Mindfulness meditation is a form of mental training. It is quite simple, yet can be quite a challenge, especially if you haven't practised it before, in the same way that lifting weights in the gym would be difficult if you haven't done it before.
During a mindfulness meditation, you are practising keeping your mind on just one thing at a time. Your mind will wander - that's just what it does, don't worry it's expected! See it as your job to notice when your mind has wandered, and to bring it back to what you wanted to be focusing on. Be kind to yourself, and try not to berate yourself for this mind wondering. After all, you're only human! It doesn't matter if your mind wanders 1000 times, practice patience with yourself.
Each time you notice your mind wandering, you are being mindful, and you are strengthening this muscle of awareness.
