Personally i find the cockpit videos quite interesting. Thought they do tend to focus on the t/o and landing bits. So perhaps 3 hours of them cruising would be less interesting.
I think wanting to be a pilot is more than about wanting to fly aircraft. It requires responsibility and professionalism. You are serving and important service to many people and i think that must provide you with some job satisfaction.
No job is a laugh a minute, but you spend a ridiculous amont of you life working, so it's pretty important to choose (or try and choose) one that you might find more interesting.
