Everything works when you do enough of it

For example

With paid ads. If we spend enough money and test enough creatives we will get enough leads

With content marketing. If we post enough and get better at it over time, we will get enough leads

With client referrals. If we got enough clients and we give em a five star experience, we will get enough leads

And with referral partners. If we attract enough of em and do a good job they stick around, we will get enough leads

Everything works

Just not in small doses
