Grow your Blog Organically. Don't force/ask anyone to share, follow or comment on blog. Just focus on promotion.
After completing your post, read it with a fresh eye from the perspective of a reader to check if you enjoy it or if it needs changes.
Image speak - A lot of bloggers tend to ignore this, but the images on your blog speak a lot for what you write. Use good quality images and make sure they express your written stuff in utmost simplicity yet precision.
