I only focus on an imaginable empty space in front of me and totally blank my mind. It's not easy, because thoughts do come back, but with practice it gets better. Those times I manage to "get in the zone" it feels like time slows down considerably, so I always set a timer for 20 minutes (limited time in the morning, etc). What is even more interesting and fascinating is that by now I've meditated hundreds of times, but every single time the general feeling is different. I guess this could be attributed to endless complexity of a human mind.
