Progress is scarier than Destruction. Nothing wrong with being scared or feeling stressed. Just keep moving forward, never look back, and enjoy the benefits of it.
this is how i look at it: once we start getting old and all our friends start looking old, we will look the most youthful because chubby cheeks is one of those things found mainly on adorable toddlers.
(but i can completely understand how our (adorable) chubby-cheek-curse could get you in a sour mood, a majority of my crummy days are worsened by my chubby cheeks.)
Congratulations on a life moving forward.
