Along with "watch me" command, the first thing I do is begin and end each training session with recall practice, no matter what skill the client and dog are working on. I also end each session with recall. I also have clients work extensively on recall throughout our course sessions as I too believe that along with making sure your dog looks at you when called, he/she comes to you, first time - every time when called. It will save your dog's life.
If my dogs never learned anything else, I'd be happy with the fact that they would come to me when called and I could save them from harm if necessary.
Additionally, "come" is easier to teach than "stay." And if the dog is young, you'll have better results working "come" first. And also, in that it is easy for the dog to learn, you can set the dog up for success and give him confidence at each training session by beginning with an exercise he knows, such as "come." And end each session on a high note - giving the dog more fun and feeling of confidence and success by ending the session with something he is proficient at such as the "come" command. Then lots of fun and reward and attention so the dog always remembers that coming to you when called is the BEST THING in his entire universe.

Recall, Recall, Recall!!!
