Hi George. I am so sorry for your loss and this most difficult time you've been through. Educating our youth is such an important and meaningful position to be in and having the drive of your brother behind you will get you right where you need to be for the youth that will benefit from you. Steemit is a fantastic place! Welcome!
P.S. Since this is your introduce yourself post you need to change the first tag to introduceyourself that way people will better be able to find and welcome you.
Wishing you many happy fulfilling days ahead and much success on Steemit!
