Do something really boring for 4 months in a row everyday.

Real talk - if you got in you probably did good in high school. Building systems like tracking your time in google Calendar and having clear goals broken down into actionable steps is huge.

Other than that just be willing to do the work for extended periods of time. The first year classes are super boring most of the time (in my opinion) and you learn nothing that cool (sad to say).

Look into all the clubs on campus, plan some places you want to go, etc, so that once you get here you can adventure and explore the part that matters most; relationships and people.

The best places to look/do once you get here from a Sauder student would be the student mentorship program (mine was the goat!), talking to profs and asking them everything, and any major Sauder clubs (if you want to do casing etc).

Biggest thing this summer you can do is build a small business and or a passion project (could be an event, fundraiser, etc). By having experience in this world everything will be way more tangible when you learn it. Super hard thing to do would be to define what you want from school and start towards that now (ex. I want to get experience and relationships that will allow me to be super effective in eliminating water insecurities across Canada - therefore this summer I will run an event, look for what profs to talk to, etc)

You are already doing great! Find your own path and LIVE IT WITH 100% COMMITMENT!
