Haha all he's saying is to chill out and take the time off. Life goes on. There's the rest of this season after you heal, next season and seasons after that. Why push your injury, fuck your knee up more and be out all together and not be able to play or ski?
That's just fucking silly. The doctor and PT told you 6-8 weeks. Do the exercises and maybe they'll get you back on the field in 6. Maybe they'll wait and keep you out for 8 or longer. Regardless of what they decide for you, do it. It will only help you in the long run.
But what the fuck do I know? Just ice it and wear the brace, you should be good to go in a 2-3 weeks.
