Hey man. Welcome to Steemit :)
First of all, thank you for your service. It is appreciated.
I saw your post after having just posted one of my own and figured I could offer some advice.
Mind you -- I don't normally share a link the first time I contact someone, but I'm going to in this case. Feel free to ignore it if you like, but I recently made a post about how to construct an #introduceyourself post and why it's so important.
Hope this helps.
God bless.
