Google Adsense can be a pain. I had given up on it until it magically decided to accept me after writing a review on a product. Did you happen to get the rejection with not enough content or was it something else? I went to your profile and noticed the amount hubs you've written. You usually need a little more than that. However, your content is exactly what Google Adsense is looking for so you are absolutely on the right track. Trust me, if I got it then you won't have a problem down the line, because MOST if not all my hubs are creative writing pieces with a mix of a few product reviews, tips and advice, and inspirational pieces.
Just keep writing. Your hubs are set up well and use pictures and polls accordingly. I would just write possibly several more articles of your calibre and quality then apply again (try for seven more solid hubs if you can do 20 even better) so they can review your new hubs. When you get Google Adsense and set up everything, just update all your hubs and post it to social media websites like facebook, twitter, and all around the web to gain more presence to bring back traffic.
