It's nice to see what comes to other people's minds when they think about any start and its end.
I immediately thought abou sex. What's better start or the end? Oh boy, the toughest question ever.
Any time we begin or start something that we really want to do, then the beginning is exciting and the feeling is great.
Finishing something that was a chore, a pain, an unpleasant activity, is always a pleasure.
Starting to exercise is good, but finishing is even better :)
