B3hr's tip to learn how one becomes humble: learn to play to support. You are now:
1. Pretty much the only person that wards on your team because, let's face it, no one wards like ever other than a dedicated support.
2. Forced to learn gold efficiency, especially since you buy wards (aka sightstone is your friend).
3. Learning that assists are, in fact, good. Not sure why people think otherwise, assists meant someone on the team got a kill, you're getting free gold for making it happen.
The above will make anyone a good player and is quite a humbling experience. Also, buy a damn ward already.
