The only issue I'd take with this is that when someone says "I feel this way," I take it to mean "I believe this but can't prove it." If you know something, or if you have a good, scientific basis for a statement... that's not a feeling. That's a hypothesis, and it shouldn't be cheapened by being stated as anything less (at least when speaking to people who aren't already familiar with it).

When you've gotten beyond "I feel like this will work, and that's motivating me" and you've moved on to "this freaking WORKS and now we have to do something about it," then you have a new set of problems to go with your opportunities.
