Welcome to the forum.
The only advice I can really give without knowing your specific problems is to start off by reading the DJ Bible. You can find it in the bottom left corner of this page.
Also, use the Search function to look for any specific situations you have questions with, and start a thread to ask something more unique to you.
The other thing I can give advice on. Try to understand why people here are giving you the advice they give you. Not only will that help you learn, but it's also important to know that not everything here should be taken as fact. You are gonna need to learn what is good advice, and what can work for you.
