Sigh... Nothing is "immediate" for me, it seems...
But, I have had an enjoyable career as an engineer. You can read a lot more of my stories in my Steemit Library... Just click on the Table of Contents GIF at the bottom of the article above...
I'd suggest the Stories and Liberty shelves for starters. ;)
I hope eventually to write a series on invention and product development. Thanks for asking! ;)
