Because I am. Therefore I will spend my days, filling my family and loved ones with as much happiness and support that I can muster until I finally fizzle out and expire. I need no faiths or beliefs apart from the confidence of my own being to sustain me in that endeavor. What fuels that desire? Something as simple as an acknowledgement or smile of apreciation(sp) from a loved one, or the return of happiness and support from a loved one. That's all the fuel I need.
