Walking. Daily. That, and purchasing good shoes. It changed my life.

At first, I was in such a poor shape (physical and mental) I was barely able to walk more than a few steps, I was also severely ill and was expected to die quickly in not the most tranquil manner. Nowadays, I'm not dead :p, and I walk miles every day and I will do my best to go everywhere I can, walking. I'm still ill (it's not curable) but it's stabilized and I feel so much better.

I'm still not an athlete and I'm old enough to realize I'll never be one but I don't care: I'm in such a better shape! Both physically and mentally (I feel so much better in my head), my endurance is skyrocketing, and I've also lost so much weight I don't need to wear 'plus-sized' clothes anymore.

And it all started by making the first step, one small step. Literally ;)
