I'll be looking at the poem in pieces, since your question revolves around how it is put together.
The first line is far too vague. Joy is an abstract thing, and I need to know more than it is on the surface. You follow with another line about anger. I understand the idea: the juxtoposition of outward appearance and internal anger, but it's done in a way that's far too vague and far too impersonal. These are both topics all poets address, so in order to the poem to read well, they must be looked at from a new perspective. Unfortunately, both of these lines are overused.
I'm not quite sure what you mean by "a face that does not cease." I like it, because it's the longest line thus far and doesn't feel choppy, but the sentiment doesn't make sense.
The comment about the smile not reaching eyes is even more confusing. Joy is on the surface, but no one sees it? Or are you saying its never turned far enough to literally look like it's touching your eyes?
A quick thing: the "to" in the life's line needs to have two o's.
Then you get into the meat of the poem: It's time to learn how to socialize. I like the premise, I truly do, but the execution is too vague. Who are you speaking to? Why are they having problems socializing? Why is there pent up anger?
As far as technique is concerned, your poem is written with an incredibly strange rhyme pattern that has no discernible purpose. The short, choppy lines make them jump out and hinder the reading of your poem.
I enjoy the hopefulness of the poem, but I feel that you can express it in ways that are not unclear and cliche. Some of these lines appear in hundreds and thousands of poems, which is an indication that this poem needs a more personal touch. Add distinct elements and imagery, as well as personal touches, and this poem can truly go places.
