From an SEO perspective, it's all about links and content. People battle over which is more important, but the right links can do wonders. You do have a good number of links pointing to the site, but they are probably not the right links. Read this recent post I did on
Link Building Strategies. I would strongly recommend spending a few hundred dollars on some paid text link ads on targeted high PR sites.
You should also change the title tag of your home page to strictly Personal Development. You also need to mention that phrase more times in your home page, try mentioning it about 10 times (only mentioned once now). The phrase Personal Development is very competitive so you need to really be on your game SEO-wise.
It's also a negative factor that your articles have dynamic page names instead of static ones with keywords in the name.
Best of luck!
