Honestly, I think it's better to let them figure it out themselves. I was actually booted out of my first uni romp because I lived on campus and spent most of it drunk (common story right? lol). This wasn't with my money...proving your point.
When I went back, my performance was high enough to have tuition covered via bursary and scholarships....with OSAP money going towards my GSXR750 lololol
In hindsight, I probably lost $500k to $1 million from the above mistakes (time wasted before climbing, potential revenue, investing projection.) Painful ****!
