Agree. In the end there is no simple answer. One should save for the future, think about the long run (in Shaggy's words). But one should also enjoy the present - but that damn tent so your family can go camping.

What should the balance be? Nobody knows. Making predictions is really hard, especially about the future.

Like my plumber said: the best time to change the old drains and pipes in your house is the day before they break.
