It is always a good time for buying PSAs. When you feel you are prepared enough to give some instructions for begginers, you are ready to sponsor new affiliates. When they have questions that you can not answer, ask your sponsor or upline. They will help you, it is their job. Listen to what they have to say, and you will learn and work at the same time.
Share your experiences with new members, so they can do the same as you did.
