Beth,
Use what works for you and throw out the rest, no matter who it's from. There is a great deal of good information on the Forum, and sometimes from unexpected sources. Listen to people you respect and silently disregard the rest. Every aspiring artist should be open to learning something from everyone. Myself, I have learned a great deal about painting, and about human nature.
Keep painting,
Renee Price
