This was posted by a friend of mine on Facebook and it's a very interesting thing to think about. I've copied and pasted her post here to see if anyone wants to join in ^_^
Every birthday, you get five tokens to improve yourself with. Each token is worth the same amount, not a large amount, but a small yet noticable amount. They can be added to your skills, your health and your looks. You could use them to be a little better at cooking, to be a little more youthful, a little better at absorbing information, a little better at reading music... e.t.c. You can combine the tokens, for instance you could use all five on becoming generally more athletic.
If you use one token to generally 'be better at German' the one token amount will be thinned across grammar, speaking, listening, vocabulary...e.t.c. The result would be less obvious than if you were to say 'German grammar' where the whole token amount would be used in improving your ability at German grammar specifically.
They can't be used on materials (you can't make yourself a little richer) or fantasy skills (you can't make yourself fly) and you can't change the past. You can only use them to slightly alter your present self. Remember you get five tokens every birthday.
What five things would you use your next birthday's tokens on?
