why invest?

Why should you invest? why put money aside? why save?

There are as many different reasons invest as there are different people:

saving for retirement
saving for a down payment of a house
saving for the education of children
saving for rainy days
saving to guard the value of the money against inflation
. . .

Why differentiate the reasons behind the savings effort?

Only by knowing your reason for saving can you figure out what type of tool to use for your saving efforts.
