A year is a lot? Then what is 5 years, a lifetime?
Let's not fool ourselves, a year is NOTHING, it passes as soon as it arrives. There is nothing bad with people "loosing" a year or two, or perhaps even more.
In an ever more pacing world, we should readjust and look back, some might "sacrifice" a year, but they also learn valuable experience so not all is lost.
Today, when people's work time can last 50 years easily, what is a year or more?
Let people "search for themselves". Let them try out the hard things, let them explore and value experience, realize if something is for them or isn't.
In the end, we learn most from our mistakes, not successes.
