At least you can find something new to love after you hate your favorite thing. If you only spent that one "month" doing what you love, then you'll be forced to live the rest of your life yearning for the chance to do it again. I'm not sure what a "month" is, but obviously it is worse than having to simply find a new hobby.
Now, would you rather have a child that acts & lives their life just like you did when you were young, or a child that acts & lives their life just like you do now?
