I think everything is depends on great communication, when i deal with any client ,i always try to digg out what my client exactly want. if we both cleared about what the process should be. then results comes out best.
I think as a newbie its very important to make yourself worhty, when any client comes to you , you have to make sure that client can trust you. they should trust that you know everything and you can slove as they wanted.
