Let's take video for instance. If you listen to other marketers and look at the WSOs it's easy to feel you're not going to make it if you don't have video. But let me tell you, I've been making a decent living online now for going on 3 years and I still don't have a video.
Sure, video is great - I don't dispute that - but you need a good product for it and you need to know your marketing first. Video is not a priority.
Same goes for all the other flashy "must haves" out there. I don't have a squeeze page or a list. And I don't use pop-ups. I don't even have a blog... just a good old-fashioned website. But I've focused on the key parts of my business like building a good product and customer service.
So don't be distracted or feel discouraged because you're not up to snuff on all this stuff.
The important thing is to build a business first with a solid plan and discipline. The rest will come in time.
