I've noticed you being quite active in the forum, and I'm glad you're struggling to get better. One other thing that I've noticed is that the number of your hand posts (or replies to others in your own posts) is very large compared to the number of your replies to the posts of others. I and many veterans here will tell you that it's usually more beneficial to type out responses to the posts of others than it is to post your hands. This is because when you respond to a hand, you're forced to work out on your own the proper action to the best of your ability rather than getting spoonfed the answer by the forum. If you explain yourself thoroughly, even if you get it wrong, people get to correct the reasoning behind your proposed action, which is really what you want.
Here's a much longer post I made on the subject. It also contains a list of what, IMO, are the most important concepts for you to be focusing on. If you're sure to write about how you think the do (or don't) apply in your responses, you'll go far.
