Is your child 17 years old and has spent too much of her teenage years developing a hobby, such as softball or horse-riding, that has no apparent market value to others? Consider a last minute fall-back plan: use the experience in her hobby as a core strand around which you can wrap some other very different skills. If it’s softball, could she use her understanding of the needs of fans and players to come up with an app or service that she knows would be wanted? If it’s horse-riding, are there some short tutorial videos your daughter could put together for YouTube and a website reviewing horse-saddles with an e-book for beginners? Build on what your 17 year old child already has or, if not, starting from scratch will set your daughter back another decade.
