How can I increase mobile checkout speed to reduce cart abandonment?

I’m seeing an incredibly slow Mobile site speed for checkout (Google Page Speed gives it a 14), and I believe it’s causing a significant increase in abandoned carts. I’m not incredibly technical, so Google’s diagnoses below doesn’t really help me. Can anyone provide a few tips on how to speed up Mobile Checkout on my site?
