The world is full of tragedies. It is only how you cope up with them. I'm super glad to know some of the screws have been removed. I hope the rest are removed on time next year and you can get some normal routine back. I think the lower back is going to take some time, but it will only get better. AMAZING talent you are, firepower. Keeping inspiring the world :)
About the experience you asked, life teaches us new things everyday, no? My life has taught me to keep space in my glass and not to let it get full. That's what I do and keep learning...
Have a great rest of the day.
