To give a different point of view, the message I got out of this was exactly what you were intending. I didn't come away with "go find opprotunities to be a hero". I found the opposite in fact, that you're saying ~don't~ go looking specifically for those heroic opprotunities. I feel that you reinforced this point in your closing statements quite well:

>It isn’t about creating bigger and bigger opportunities for yourself — it’s not about selfishly inventing self-serving projects. Rather, it’s about getting better at recognizing and taking advantage of bigger opportunities which are already there and just making things happen.
