It's not a puzzle with pieces missing or lost.
It's a high school locker with a combination lock - and we have to find the right sequence to open it up.
Inside we will find the specialty subjects that interest us most, and the ones we find challenging.
But if there is someone there to use the ones we like, the ones we could think about all day long - to make the difficult ones easier, we'll soon catch up.
You might have to learn a bit too - quite a lot to be able to help us.
No one says it's going to be easy, it will be very challenging. But very satisfying.
But just because we know the combination to this one - doesn't mean it will open the next.
Everyone of us is different. Some will open easily, some will take a bit longer, a few more tries.
You might even need to go ask someone else how they did it, and see if it works for you.
But we are all worth it. All we need is the right help.
