There are many qualities that will help you be successful in this business.
BUT, there are a few which are very important.
Persistence - the ability to keep working at it even if results aren't coming in as hoped. Eventually they will but only if you persist.
Enthusiasm - your team will take notice of you and follow you if you show real interest in your business. If you aren't excited, why should they be ?
Helpfulness - be sure to make a connection with new sign ups, provide help to all your team, keep regular communication with all your team and pay particular attention to those achieving results. Your success is completely dependent on their success. Your job is to help them every way you can.
Leadership - Its easy to tell people what to do but not very effective. The best and most effective system to achieve good results from your team is to provide yourself as an example. "Do as I do rather than as I say". How successful will duplication be if you dont provide something for your team to duplicate ? Be a leader that they can follow and help them to follow you.
