I would say do not lose sight of the big picture. The topmost responsibility of parents is: To prepare them for adult-hood.

The following cross-cuts anything the child decides to do in future:

1. Being mentally tough

    * Dealing with success & failures
    
    * Dealing with conflicts

2. Money

    * Importance of money & saving

    * Importance of investing

3. Communication skills

    * Focus on effectiveness of communication

    * Importance & ability to sell

Edit: Its fine that as a parent you might not be well versed with all of the above. I am certainly not. Learn along with them. I make my deficiency in certain things e.g ability to sell as example to my kids to not to become like me.

Edit2:

If you have male child:

   * Teach them how to be respectful towards women

If you have girl child:

   * Teach them to be financially independent

To both:

   * Teach them that beauty is not permanent. It has short shelf-life and it quickly loses its utility after ~35. All that remains in later age is personality.
