"RE is the best investment when fits your life style".
An investment, no matter what it is, that fits your life style is the best investment. Some people invest for fear (e.g., of becoming poor after retirement), and some people invest for greed (e.g., of maximizing profit of their every penny). I try to remind myself that nothing is more important than the life itself. What I have and what I feel at this moment are not going to be there forever, enjoy them now. In the meantime, work for something I really love and want it happen in the future.
