Any advice regarding any topic that a 22 year old should know? Or what would you tell your 22 year old self?

Don’t be lazy and just do the necessary to apply for the overseas student exchange program :p

My advice is rather personal. So I highly recommend that you read “_What I Wish I Knew When I Was 20”. _The insights there will blow your mind and shift your paradigms

Grab every opportunity that come by (if possible), exposing yourself to these opportunities will give you an edge over others. Open as many doors in your life because some day, some time, doors will close, so always have more than 1 avenue for you. Dab your toes in various stints, try out different things while you can (except the vices), so that you can eliminate what you don't want in life. What you have at 22 is time, so spend your time wisely. Read a lot, mingle with different people. Think long-term, don't be overwhelmed with the short-term stuffs :)
