I know the feeling, you are on a high and want to improve asap, but....muscles break when pushed, ie running, in a youngish person they need a day to recover and an older person needs 2 days to recover. quality training with plenty of rest inbetween............must remember to do this myself!!!
However do what you enjoy, variety is the spice of life, gentle hills then build up to longer steeper hills, once you can run 30 mins comfortably start increasing speed once a week.
Just be careful as it is easy to over train at this point, you will lose all your energy and it will be like pulling a tank, so the 10% rule is a good one, go a bit over sometimes but not too often, listen to your body, but above all enjoy your running.
