This is a great question, and it really depends on your situation. Here is my usual advice:
Our studies show that the average Network Marketing Professional works somewhere between 7 and 14 hours a week. The problem is that the majority of these people feel that less than 10% of their work time is truly effective.
LeadTrain allows you to be more effective and waste less time. I tell people to spend 30 minutes a day completing tasks and advancing their network. You should be able to advance many contacts everyday, and thereby be doing more than ever before, in less time!
So, you can use LeadTrain as much as you want, but we recommend about 30 minutes a day!
