I have a post on here "doing it my way" that I have been trying to keep current. The first post has links to my prior posts. Not a lot there since I didn't post a lot, but the transformation in my thinking is pretty obvious.
I am afraid of heights also...so it is better that you have a pro do it. I can overcome the fear...but I have also done 20-30 roofs in my lifetime...so it takes me only a few minutes to control my inhibitions.
On changing the scenery....I have found some easy changes even can change things. Recently because of Christmas we have rearranged the living room three times since Thanksgiving. Each time the room feels "different"....more inviting. The furniture is the same...but the layout changes the atmosphere.
