Mind wandering during meditation, monkey mind

This question is for experienced meditators. I’ve been practicing for a very long time, meditating often, yet I still notice my mind wandering all the time. I struggle to sit still. My mind is always trying to escape from this place to another. I’ve been recommended to simply watch the mental activity and wandering, but the mind wandering takes me away and I forget to observe. It feels straining to be in the moment. How should I approach it better?
