Just because you don't break, doesn't mean you don't overdo it. Very easy to burnout on high mileage and fail to realise because the pace is easy.
Train wisely, plan a season. Do your workouts when the time comes. That's it.
Yup, second this. I would consider your (OP) premise of "uninjurability" as a nice foundation, with probable scientific reasons behind it, not a carte blanche. I would stick with sound practices and do all the usual periodization, base building, all the nooks and crannies you'd expect. Usually, the problem for a lot of us are the unexpected major and minor injuries etc. along the way that complicate even conservative plans and require lots of readjustment. Keep doing things like active recovery, stretching, work in the gym, muscular balance, good sleep, good nutrition, a balanced life in general, etc.
Excitement is a long term thing... reflecting on your vast life and experiences and dreams. The joy of doing these different fitness activities day to day. Body health and betterment and being out in nature. Being amongst positive people. Keeping up with the Joneses in the brute way, although partly necessary, is also shallow and not where the real joy of life is. Social media, college, dating, internet message boards, runnerspace, etc. are at best, minor stepping stones. Lose sight of bigger things and get lost in these minor artificial trifling things and you'll lose the emotional and spiritual depth. That depth is wedded to the depth and potential of the running lifestyle over the long term.
Train your mind, your aspirations and your emotions, too.
