Can meditation really help..?

Busy life and hectic schedules are the two common things,which every human being is facing these days. Meditation is a emerging as a holistic approach to come closer to spirituality. It is said to be a positive trend which is attracting everybody's attention. But does it really work..? I don't know.. I live with the kind of life style which doesn't allow me to engage in such activities..
I believe someday.. I will surely start this spiritual activity.
