Learn what YOU need to improve.
There are lots of Youtube Video's now days that will help you learn a lot of the basics of photography.
You will need to do a lot of searching and sifting, but eventually you can learn what you need.
When I started out, there wasn't a "Youtube" to learn. Instead I had to figure it out pretty much on my own.
Now, you can take all the wisdom and experience I have learned, and design a study that will allow you to focus on what YOU need, not the masses.
