A couple of 2p's...
My neighbour teaches A-level photography and she is often asked questions like this.
She says that learning at distance courses can be OK, but ought to meet independent standards so that there is verification that the teaching is up to par. She also says that for the money it is preferable to get some sort of achievement/qualification to take forward to your next step.
It is worth giving camera clubs a go, but they can be very variable
Visit a few and see if you click with the attitude at any of them.
The most useful thing I believe you get out of a camera club is seeing other peoples work that they are proud of.
You may often wonder why they bothered putting their image into a comp and you may be mystified why your own images don't get unanimous praise - it's a valuable lesson about humanity......
A classic illustration is our club's enprint challenge which is voted on by the members. Each member gets 4 votes and there about 30 people voting.
The winning image will often get as few as 6 votes and very few images get no votes
TP is a great resource; use it
Put images up for comment, but see my earlier comments about camera clubs as you often get completely opposing opinions. Bask in the praise and be prepared to ignore opinions you don't agree with; everybody has their own opinion and both of you are right.....
Get along to a TP meet - I believe everyone who goes to one learns something new.
