Yeah, yeah - I understand it is all subjective. I guess its all about risk management and risk tolerance. I try my best to ensure I have as large a margin of safety going into the deal (buying below market value) and also a good margin of safety throughout the investment life (only investing in areas which have a great chance of growth due to infrastructure, population growth etc...) I can only dream about the day of stopping - but when that day comes I will hopefully start to pay off all debts and hold unencumbered assets.
