Getting started in Mortgage Industry.

I used to post here a lot back in the day, and boy the site has changed..  I haven't posted here in a few years and took me a minute to find my way. 

I bring you today some interesting topic to provide perspective on. I have been working in the IT sector for about 23 yrs now, and doing well professionally and financially (both in my W2 job and real estate investment properties I have self manage). I do still find myself open to the idea of creating more options for myself, so I can live life on my own terms.  Like most people, I don't hate my employer or the work I do. On the contrary I love my employer, folks I work with, and the job that I do.  I just don't have lot of flexibility, which is what I want. 

So I was thinking about getting my NMLS license and working with a lender, while still keeping my W2 job.  Not looking for anything high paced with 50-60 hrs to put in a call center environment, as I don't have that kind of spare time, but to learn and grow at my own pace and develop clientele.  Just the way a lot of realtors start out.. FYI I used to have a real estate license from 2015-2021 but gave it up as I wasn't using it that much and plus I detest driving. 

I don't need to be paid a single penny for this. Just need to be shown how to do things and allow me to grow at my own pace. 

Any thoughts on where I should begin?
