That is a very wise statement. Something I picked up from ET a few months ago: there's a difference between a trader and an investor. Putting them together, daytrading IMO requires the most backtesting; if you haven't backtested well, (don't be a "daily trader" rather) be an investor.
BTW, an example I heard about giving in relation to the afterworld:
Everyone sits at the same banquet table opposite one another. We all have straight arms & and cannot partake of any food ourselves; all we could do is feed the one opposite us. Those of us who developed the attribute of giving will feed the one sitting opposite him, & will receive back. Those who didn't, will starve, and sit before the finest food in torture.
