For society: successful daytrading allows for the freedom of the individual to "give back" what he wants because he has the time to do it....contributions to charity (Sept. 11 fund, Cancer and AIDS research, etc., we can take time to train for various running events such as a 5K for Family Advocacy issues and finally on Thanksgiving or other holidays, we can volunteer time to work at a soup kitchen, etc.
For family: We have the freedom to never miss a baseball game, basketball game, dance team performance, violin concert or work with our children on their homework when they need it.
There are plenty of contributions to society that we can offer that don't necessarily have to be by "creating a product" or "offering a service" directly through daytrading..it's what we do with our free time that shows our "value" to society..and for me..more importantly...family.
I'll never forget all the time I had with my step daughters coaching their soccer, doing their projects for school with them, taping their tennis lessons or their concerts and performances.
Daytrading doesn't offer anything tangible..it offers us the freedom to explore other ways to "give back" that many other lines of work wouldn't have a shot to.
