If you've heard about mindfulness and are curious but don't know where to start or can't afford classes/sessions, you could try reading this article: http://www.mindfulnessmeditationinstitute.org/2013/01/meditation-for-beginners/
I have meditated off and on since I was a teenager. I am a big believer in it and it really helps me get grounded, but it does take time and practice to really feel the impact for some people. Be patient with yourself. Don't expect to reach Nirvana right away.
If you would be interested in some guided practice, please contact me.
