There are several ways to go about this...
You could outsource the articles you think are difficult. People will help provide text for as low as maybe 20$ - then you can add photos & videos, and publish it afterwards.
Another thing is planning your content. Once you are experienced, you will know a good recipe is: intro - content - photo - video worth sharing (from YouTube or some other source) - content - a quick recap and then a comment field.
Finally, focus on content. That will always be the main thing in attracting more visitors to your hubpages & blog articles.
Have fun & enjoy the process. Once you find your passionate niche, you will be turning out hubs in no time. :-)
