I read a great blog post by Alexis Ohanian titled Getting Things Done > Grade Point Average
It talks about a point that I always knew: Your grades do not matter as much as getting something done. I intuitively knew this while in school taking computer science. I had friends who had horrible marks, but they were the smartest technical people I knew. Then there were others who somehow got the marks but could not solve simple undefined problems.
I think the biggest benefit of school is that you are surrounding yourself with people that want to do great things (learn, contribute to society) but you can also find these types of people at meetups, conferences, IRC rooms, etc. (you just need to be resourceful).
I have seen so many promotions, new clients acquired, money raised, etc from being resourceful. These people navigated waters unknown and got things done. This quality I strongly feel out weighs a persons marks. If you also have interpersonal skills – you have a killer combination.
On a final note, I love this quote:
“You are the average of your 5 closest friends.”
Surround yourself with great, passionate people and you WILL do great things.
