You've got an interesting blog, especially the training stuff with your ACL.

I noticed you haven't done an introductory post on Steemit yet.

It would be well worth your time doing a post to introduce yourself (who you are, what you do for work and hobbies), and what you post about on Steemit using the introduceyourself tag.

There's also a good Korean community here who post under the kr tag. I'd also use this in your introductory post. Another tag to use is travel, which you have been doing.

Your introductory post is likely to get you a decent number of followers, along with good use of the travel tag.

I'd probably spend less time doing daily spending videos, and perhaps talk more about what you are doing in your time in Vietnam, such as tours and sights and your nights out partying etc.

Anyway! Keep posting and creating original content! Steemit needs good content creators and you're well on the way to being a fantastic contributor.
