The Blogger


Hello! I am Tina, a thirty something nurse-turned-defense-analyst and working law student who loves to write and, hopefully, make a steady and decent income out of it.

Check out my writing portfolio here.

Welcome to my humble nook!

I am the author and founder of The Open Concavity Blog

I know my blog sounds ridiculously paradoxical, but I guess that pretty much sums up my life in its entirety – recluse in my CONCAVITY but very much OPEN to so many possibilities.

Thus, the blog title “The Open Concavity”.

So what do I write about?

I write about five niches closest to my heart owing to the fact that I am a woman of multiple trades and interests.

I frequently post about my bible devotionals, law school journey, health and lifestyle, and my opinion on politics and defense.

My faith in God and life as a Christian, devotionals, and inspiration


As a renewed daughter of the Lord, I use this blog as platform to reach out to anyone who would like to connect with the Almighty.

I write about my reflections on bible verses and my perspective in Christian faith in general while making sure that I live by every single word of it.

Whenever inspiration kicks in, I also write motivational posts. I share useful stuff that keeps me motivated, which I am pretty sure can keep you going too.

Law school

I started this blog so I can have a sweet escape from the miseries and toxicities (I am not even exaggerating!) of law school. But what started merely as a diversion rekindled my interest in writing and passion to reach out to others.

I document my law school journey through this blog. It is my own way of reaching out to my fellow law students and friends, forging brotherhood (or sisterhood) with them, and showing them that we have allies to get us through in reaching our lawyer dream.

Defense analysis, territorial disputes, and national security

Meanwhile, the defense research analyst in me makes me write about articles/blog posts on anything national security, territorial disputes (particularly in the Asia-Pacific), insurgency, terrorism, and violent extremism. For the most part, I write for other national security publications and online platforms.

Whenever I’m lucky to grab a copy of my published work, I post them here too. You may read some of my works here or go to the PUBLISHED WORKS tab found on top of this site.

Health and Wellness

Didn’t I mention I’m also a nurse by profession?

As such, I always have this urge to care for and help people live a life of bouncing health and wellness. So, expect me to write about some health tips and road-to-wellness kind of stuff here, which I would normally intertwine with my law school blabs.

Beauty and Lifestyle

Finally, if you happen to see blog posts on bags, make up, skin care, and other things beauty and lifestyle, don’t fret.

You’re still in The Open Concavity; that’s the girly Tina who’s writing.

Blogging, writing, sharing, and connecting through The Open Concavity

The Open Concavity About

Writing about and tending 5 niches is never too much if you have the passion to share with others.

I started this blog as a diversion from law school and other stressors. I didn’t once imagine that this will turn to something beautiful and bigger as this.

I find refuge in writing. I write about the niches I mentioned above whenever I could.

But what really makes me happy is helping others through my writing.

I am happy that my blog does these.
