Yo Phi,
If you’re interested in improving your marketability think of yourself as a brand. No one knows you or your brand better than you. Just like a major brand (Nestle, Clorox) be careful what you publish or say on social media.
When you meet people, even in informal places (grocery store, Wal-mart) make sure you represent your brand. As a SVP of Human Resources & CEO of my company here in LA.
I’m always recruiting people that value their brand. Yo!!
