If you really understand IT, then you realize there are no easy answers to those questions.
I have been in the business and IT worlds for over a quarter of a century. Do I know a few things about computers? Um, yeah.
But then according to @RyanReese - who has been in IT for a few years…
So there you go! 
I am an expert in lots of areas of IT and business, but…
1.) Can I recover from a late-in-life job loss? I’m not sure…
2.) Are my skills transferable to the next employer? I’m not sure…
3.) Can I convince some small business that all of my years of business and IT knowledge is worth more than a $500 WordPress site? I’m not sure…
4.) How can I indeed convince other people (businesses) that I am worth $______ so that I meet my family financial responsibilities that my former job used to easily cover? I’m not sure…
That is why I am here!
