Your first 1,000 leads are the hardest and the most valuable. They teach you who actually wants what you're selling, and that lesson is worth more than the leads themselves.
Start with one offer and one funnel. Resist the urge to build five things. A single lead magnet that solves one specific, painful problem will out-perform a vague 'newsletter' every time.
Then go where your people already are. Borrow audiences before you build one: guest posts, podcast appearances, partnerships, and genuinely helpful answers in communities. Every one of them should point back to the same funnel.
Measure ruthlessly and double down on what works. Most channels will fizzle. One or two will quietly produce most of your leads, and your job is to find them fast and pour fuel on the fire.
