How do I handle large paragraphs of centered text?

I've been working on a very simple portfolio website for myself and the template I'm using is center justified for all the text. I have a bit of a blurb about myself and I don't know if this is the best way of dealing with so much center justified text. It feels a bit awkward on my eyes to read. Am I just imagining things or is there a better way to do this?

EDIT 1: My website is based on this free template, which also has some larger sections of center aligned text. I would like to left justify the text, but I don't know if it would fit in well with the way the rest of the website looks.

EDIT 2:

So I've flipped the colours so it's black text on white. This is what it looks like now, with a sens-serif font too. I've also included what the link looks like on that white background - I may need to darken it a bit:

EDIT 3:

Okay so left justified, with my attempt at bullet points. I'm going to sort out that soon. I need to set the font size correctly, but you get the idea.
