IMO, a more logical approach is to let your thoughts flow and simply observe them instead of trying to control them (that never worked for me.)
It’s a bit tricky because sometimes you get caught focusing on being the observer and letting sensations pass. It’s a more subtle thought but as you practice those subtle sensations become more apparent. It’s a useful sensation in the beginning to let the more “coarse” sensations and feelings go but eventually you need to let that go too.
