Simple Habit: Happier & Healthier

I have a goal of a happier and healthier life this year. One of the ways I have been working towards this goal is to practice mediation. Mediation is practice best done under the guidance of a someone who builds these practices with a purpose behind them. However, what I may need from my mediation changes so I was looking for practices that could change with what I need. I also am a low on funds college student so if I could use a service that was free it was all the better for me.
