Good insight. I'm a believer in the multiple streams of income model. Work, investments, life is cyclical. Business and industry and markets ebb and flow. By not having all of our eggs in one basket we offer ourselves wiggle room and the ability to ride out financial storms.
Wiggle room is important and I think preparing for the future is keeping resources aside for when opportunities arise, there is some wiggle room to take advantage of them. Too many are caught with nothing when they need just a little.
