I have a set of prayer beads and I used them for the first time a few days ago.  If you're having difficulties praying, meditating or whatever else, I would highly recommend that you buy some prayer beads.  They go by many names.  Malas, komboskini, chotki are 3 of the most common, by my own limited research lol.  The set that I have are equipped with 50 beads.  I need a bigger set for sure but you can keep circling if that's all you have.
