"4" means you are happy (just not "very happy" yet)
At a level “4” on a scale of 1 to 5, you are quite happy, which is good, but something is probably missing that is preventing you from being at a level “5” (or perhaps there are several things missing). You probably enjoy life, work, and other people, have some good relationships, and you’re optimistic about the future.
