Hard Work
I have been able to listen a few times lately to Neal Boortz, and while I don't subscribe to everything he says, I do enjoy hearing him talk about things like the Fair Tax and the importance of a strong work ethic. Today he talked about 80 hour work weeks and driving home in the dark.
I just don't think its possible to attempt and achieve great things (or true contentment) without proper dedication to hard work.
Three things are necessary:
1. Discipline: Working harder and longer than anyone else.
2. Perseverance: Fighting through adversity and negativity.
3. Discernment: Making the right decision, at the right time, for the right reason.
Especially when no one is watching.
