Hiring an expert is the way to go if you want to do this fast and effectively. In the long run, new clients are worth more than what you have to pay to get help finding them. You’ll make far more money on one turned lead than you will spend on getting someone to help you get that lead. If that’s not the case for you, however, then things may need to change a little. You’ll want to go do some looking at reviews for various lead generation companies to see what they can help you with and if they are worth your time to work with.
I believe the ones that don’t make it in the industry (if they chose a good one) don’t give it enough time (like you said they quit before a year is up) and commitment to doing what it takes to grow. I don’t spam FB and only 2 family members order product but I have at least 100+ home school moms making >$2000/mth. Some team members make more, some less. It’s what they put into it (business wise not monetary)
My network marketing Leads are the best way to follow the golden proverb that somebody must have dropped coming down the mountain, because when it fell, it hit so hard that everyone doesn’t think twice about it just being plan common sense. And I don’t know why it isn’t folded into every California cookie because it is the best way to gain a fortune. This proverb that needs much repeating is “Work smarter, not harder.”
