I see from another post that you are a runner. You come in with the significant advantage that your body is generally in good shape and you understand discipline. The second paragraph of your post here is mostly true for the first 6 months, then you have a gradual modification/losing of the rules. The objective you are running towards(yes, pun intended here lol) is labs every 2 or 3 months, an yearly thorough medical evaluation and maybe a pulmonologist visit every 6 months. Meanwhile, you will be building up/training your new lung to capacity and returning to your pre-transplant life. BTW, I've had horses all my life and after a few months, trained back to riding plus doing barn chores. Yes, there is a good life for you "on the other side" of the transplant.
