1)
Remove render-blocking JavaScript:

blogger.com/static/v1/widgets/3392677022-widgets.js



2)
Use asynchronous versions of the following.scripts:

apis.google.com/js/plusone.js





3)
Optimize CSS Delivery of the following:

blogger.com/…c/v1/widgets/521441841-css_bundle_v2.css

maxcdn.bootstrapcdn.com/…t-
awesome/4.7.0/css/font-awesome.min.css

minutes)

Compressing 1.bp.blogspot.com/…
cOwCLcBGAs/w506/nity
%2ong.jpeg could save 20.1KiB (30%
reduction).

Compressing //1.bp.blogspot.com/…

reduction).





5)
Prioritize visible content
Your page requires additional network round
trips to render the above-the-fold content. For
best performance, reduce the amount of
HTML needed to render above-the-fold
content.

All those static contents are hosted by Google themselves so you can't do anything about it.

Consider moving your blog to a self-hosted WordPress blog/site where you have full control over optimising not just with the static content but everything.

Yea, I would also recommend perhaps hosting your site on your own Wordpress blog, and administrating your own server settings may increase your speed in the process. I use caching and also page compression on my WHM settings, which allows faster page loading speed, as since compression would compress your entire site into a compressed form before sending to your visitors, the compressed form = smaller file size, faster transfer, thus that would enable loading your site faster in the process.
