mi blog takes 10 seconds to load

Hello,
My wordpress blog is currently running at https://www.the-mistaker.com . I installed a theme I like a lot. I thought it would load fast because it’s a pretty simple one, but it’s actually taking 10 seconds to load. I’ve tried in several PCs and it never loaded faster than 6 seconds. I would like to start writing, but people won’t enjoy waiting so much for content.
Could anyone help me? I’d be so grateful.
Thanks in advantage.
Raisa.
