@thatmanphil Hi,
since i came to learn chess at old age, i may be able to give you some encouragement. In order to learn chess, several things seem to matter:
interest/motivation/time+effort:
learning to play chess at a reasonable level is no walk in the park, and some time is necessary just to give your brain the time to build new circuitry. Of course, if you have unrealistic expectations (like say: gimme that pill, i will swallow it and be world champion in no time), that will not help, but it will seriously affect your long-term development.
Apart from that, there is
Learning methodology:
To me, it was very helping to start off easy (only simple endings, learn to coordinate few pieces only, later including pawns,...) and to approach tactics from a thematically organised side. Only at the very end will openings even come into consideration. During the whole time, you should take care of the vulnerable plant called "fun". Otherwise frustration will get a grip on you.
And the environment, you find (or set) yourself in, matters: chess friends, coaches, a spouse allowing you to waste time. For me, it was helping a great deal to not have computers at the time, and only temporarily engaging into a professional job. So i had huge amounts of time to spend!
I think, if you are not progressing, there is something going wrong, Just as making love without giving birth to a child is somewhat "not right" ;-) What comes to my mind first is:
Addictions:
Alcohol, Internet, Computer games, and more seriously tend to inhibit our ability for self-controlled behavior. Blitzing can be such a detrimental habit.
IMHO, it makes sense to look into the reason/motivation that lets you desire to improve in chess. What do you want to archieve/get from it? It is not necessary to be good at chess to live a happy life!
