What is success to you? In my travels, I've found that success is always fleeting because it constantly changes as you accomplish each of your goals. Of course, that's just my personal take on it.
As for the inspirational quote:
"Obstacles are those frightful things you see when you take your eyes off your goal." ~ Hannah More
Don't know if it's my favourite (there are so many wonderful ones), but it ranks up there.
~ Teli
