Do a Google image search of Earthrise. Then search for Pale Blue Dot. Those two things are some of the most awe inspiring and staggering images I have seen in my life.
Basically, astronomy gives me feelings.
What I would tattoo on my body:
"For small creatures such as we the vastness is bearable only through love"
"Books break the shackles of time. A book is proof that humans are capable of magic"
"We are made of star stuff. We are a way for the cosmos to know itself"
Also, maybe an old fashioned heart tattoo with the names of my nieces in it.
In my opinion, being able to laugh at just about everything is an incredibly important talent. Life is pretty damn funny when you think about, and I find that humor whenever possible.
Also, I am good to people and things. So there is that.
Further, I am not good at writing. Simply read on for proof of what happens when you ask someone with ADHD to fill out a profile. Central themes? Coherent narrative? Structure of any sort? Not gunna find it here.
