It can be very difficult to start building projects when you already do freelance work though. It can be very distracting plus it's probably going to be a while before what you could earn from a product gets anywhere near what you are earning as a freelancer. That said I don't necessarily think your advice is bad, it just depends what you want. I say this as a freelancer currently working on some products as well.
