Well, there is no method that's 'better' than others and really, nobody can help you with this. You have to find out your own method. As they say, when you are ready your method unveils before you by itself.
But let me just share you some of the methods that has worked well for me.
One way you can do it is through self enquiry. First watch your thoughts, and as you watch your thoughts, ask yourself to whom does these thoughts occur. And then ask yourself to whom this thought of enquiring about "whom these thoughts occur" occur.
Confusing eh? But as you go on this way you will ultimately find out that you are just a witness watching the endless stream of thoughts without any judgement and without getting affected by those thoughts.
Another method is to watch your breath. Watch your breath as you inhale and exhale, as it rises and falls, and again as it rises and falls. Don't try to control your breath, just watch your breath as it rises and falls, rhythmically. And don't try to control your thoughts. When your mind wanders, just watch your breath again. Just go on this way and see what happens. Your thoughts are powered by the same same energy that powers your breath. When you get hold of your breath and thereby the energy that powers your breath, you get hold of your thoughts.
But the best method, I think is not 'trying' to apply these methods
. Just be aware of these methods, make an intention that you are going to be a witness watching your thoughts without judgement, and just, just let it happen to you.
