Well you definitely caught my attention with your profile writeup, my friend! And I've been writing all my life and still can't say I've figured it out. Any author who says they have is lying. It's a real struggle to even clearly convey what you want, and then to make it interesting...that's another struggle. But at least you asked that question, and that takes you close to the answer.
btw, If you like humorous novels such as Wimpy Kid books, do check out my book
