I prefer long term; I've my pension and house sorted at 30, and will be able to retire early.

But I live pretty cheaply, and earn a decent income. When I'm saving for something short term (a holiday, new tech, etc) I usually just pick up a couple hours extra work, or don't over-pay into my savings/mortgage that month. I think if that wasn't the case saving for the shorter term, more experience-based things would be the priority in actually enjoying life.
