I'm looking forward to reading more of your future posts. I can completely relate to your comment about age being just a number. It's definitely not too late to get started and learn something new, and with continued effort I'm sure you'll be able to learn even more.
I have an education background myself, and similar to you I am trying to learn new things at a later age in life than most people would, so it will be good to compare notes as we both keep learning and trying out new things.
