I learned this while working with children with learning disabilities or diagnosed with autism. I noticed significant changes in their responses when I led with compassion versus sternness.

Tip #1 is the most crucial and honestly the most under rated. That my friend is water. I stumbled on this tip accidentally back in my junior high days. Although I didn't have skin concerns at the time, I was a chubby kid and I thought if loaded up on water it would cause weight loss. SILLY ME.
