It is so hard to find balance these days - the world has gotten easier in many ways, but for some reason many of us find it more stressful.
If I think back several years when we all weren't hooked up to cell phones, beepers, ATM machines etc. - we had MORE TIME! I don't get it.

Depression is prevalant with many it seems, and for anyone who has not suffered from a diagnosed clinical depression - it is hard to understand.

But as many of these replies have said - exercise is certainly a real key in helping you feel better. Whatever your situation, whether you have access to a gym, or prefer to jog or bike - just try to do at least 30 minutes a day. It might not solve everything but it will kick those endorphins into play and you will benefit from looking better and feeling healthier.
