Network interfaces can be Ethernet ports, wireless adapters, or linux network engineer virtual interfaces created by software. If you thrive in the IT world, network engineer roles should suit you well. However, you might have to juggle many technical tasks concurrently, which could feel stressful.

Music can be nostalgic, expressive, and therapeutic. It can be loud and fast paced or quiet and placid. It doesn't matter the genre, music is a part of me. I love the way that music can pin point the exact emotion that I can't quite put into words, or the thought that's on the tip of my tongue. Whether it's the intense beat of Linkin Park or the soothing strums of City and Colour, I rely on music to keep me going.

My playlist goes from pop to punk, country to orchestral - I don't discriminate. The soundtrack to my life is spontaneous and quirky, much like myself.

"Don't resent me, and when you're feeling empty keep me in your memory. Leave out all the rest" - Linkin Park
