No, you wouldn't be a moron if you have a good business.
Yes, I tried that before. Was bringing in about $40k/month from software, and living good. Did what I thought was smart, and continued to invest in myself. Then 9/11 hit, and my sales literally dropped by about 80% overnight. Everyone became petrified, and closed their wallets.
How do I know for example, Israel isn't going to strike Iran, and Iran doesn't already have hundreds of people living in the US who will blow themselves up upon order in malls and subways, causing mass panic, and a drastic decrease in my cashflow? I mean, if I was Iran, that's exactly what I would have been working at over the past several years.
I'll just continue saving for a rainy day instead, thanks.
