Thank you for the upvote!

You are not supposed to ask for up votes here at steemit. Later, when you get more power, people will see you and downvote you so you do not want that.

Search for "how to comment on posts" for ideas.

But in general - write a few sentences about what you see in the post and tell the person if you upvoted or resteemed to help them. Then they might follow you anyway.

For example - on this post - what was the most amazing thing you learned?

Good luck!
