How do you keep your mind still? I've tried counting my breaths up to 10, one for in and one for out, but honestly, it's a lot harder than it sounds. I end up having to start from 1 again a lot of times.
Keeping the mind still isn't the point, nor is it possible without effort. Effort isn't really what is being indicated when experienced meditators talk about "stillness". Meditation is fundamentally extremely simple: focus on the chosen object of meditation, notice when distraction has arisen, return the attention to the chosen object of meditation. There are many useful paths/methods/techniques that can grow from this soil, but these should not be understood as goals.
Counting is thinking. The idea is to not follow wandering thoughts. When you get it your mind is silent, and you are fully present. You can hear everything around, not even a ninja could sneak up on you.
I suggest not counting. Don't use your mind to tame your mind. Try to ride a tiger and it will only eat you.
Escape conceptual thought entirely.
From what I understand, it's slightly different from escaping conceptual thought entirely. The idea is to not direct your thoughts, but rather observe them without judgement as they arise and fade away. So the idea is balanced observation, and this is easier to do by relaxing your mind and body.
