Puppies have crazy amounts of energy. The first year can be really challenging. I highly recommend daily walks and multiple brief training and play sessions throughout the day/evening.
Having a schedule, a routine, has a calming effect. Try to do everything at the same time each day so that your puppy knows when to expect things and when not to.
Every dog is different, but for Max, getting angry at him hyped him up. It was much better to ignore him...or if he was doing something that needed to be stopped, we put him in the xpen. For instance, barking inappropriately -- we corrected him in an even voice and if he continued, we left the room. He quickly learned not to make us leave the room.
Lots of good advice in this thread. I hope you find what works for you and your pup.
