Does it matter which meditation technique I use?

In Zen there are a number of techniques that are commonly recommended. Among them are attention to the breath, counting breaths, slow mantra repetition, fast mantra repetition, and holding a question such as “What am I?” I usually recommend working with a great question, but any of these methods can be effective for a given individual. It is best to work with a teacher to choose a practice that will work for you. But more important than which meditation technique you use is how dedicated you are in your practice. Once you have settled in with a certain technique it is important to stay with it and not jump around trying other techniques, committing yourself whole heartedly and persevering through the inevitable dry spells. Then your practice will be like water dripping on a rock. If it always drips in the same place, eventually an opening will appear.
