The easiest way to do that is by communicating with your team each week, thus keeping them motivated. Also do have your SFI gateways advertised, to be able to get new sign ups.
Secondly, maintain your EA either by having a standing order which is the easiest, or by buying some stuffs you need that will get you at least 1500vp.
With any of the options above, be rest assured to get your commissions and as well as having your team growing.
