Meditation is all about controlling your concentration and attention. It certainly helps, heaps. Speaking from experience. Please try it. :)
(Although I also attacked the lack of attention span problem by doing totally seeminly dumb tasks such as reading a book backwards which makes no sense and really forces you to re-focus all the time. From a few minutes I was able to get up to 10, and later 15 minutes per time without huge mental wandering. Same goes for meditation, from minutes to tens of minutes with ease in a matter of weeks.)
