I am not an experienced web designer or writer so please take that into account when reading my first impressions. I am a non-English native speaker.
Seldom I am visiting sites about self improvement and such but I think your site has a unique combination of subjects.
The articles have a serious character but maybe this will be appreciated by your target audience. Personally, I like to see bit more humor and a tad spicier kind of language while being professional at the same time.
Some articles are a bit long in my experience, after 500-600 words I almost always loose interest no matter which subject, but that's just me. Other than that, the language and grammar etc. are setting the standard for me as newbie webmaster.
The site loads quick and I have no problem viewing it on my tiny 1024 * 600 screen. The design made a religious first impression on me but after browsing through the site seeing I see it more as a spiritual template. (the arrangement of the double plus reminds me of a cross). I like the width selector in the top right corner and the clean and readable design overall.
I can't really rate the site on a scale because I don't know where to measure against. But overall, the site is what I expected from someone like you as one of the best site reviewers on Netbuilders.
ps: What kind of audience you are targeting?
