I agree that it makes much sense to try and get the most from your money. I think there also need to be a balance between being stable (able to pay needed expenses) and what is extra money for investing, trading, etc.
I usually take 10-20% of my income and disperse it among several investments and income producing/speculation. and what about HBD at 15% APY?
