We all have one shot at life and as such, I believe in living life to the fullest. This means constantly stepping out of my comfort zone by visiting new places and trying out new things. My relative success on Udemy has given me both financial freedom and the ability to be location independent. I am currently travelling around the world spending about a month in one city (current location is Chiang Mai, Thailand) before moving on to the next. 

My hobbies include watching movies, sports and playing chess. I am also a huge Dead by Daylight gamer.
