Shakespeare can teach you how to survive the emotional dangers of love. The sonnets are instructive as much as they are beautiful. They are about how a poet can rise above their status through truthful expression. Love is a driving force, but it has many dangers and downsides. 

The first most important thing to know about love is that the love of self is the primary component. While the poet is humble and knows that they have less status than their beloved, the power of that love emanates from within the poet themselves. Though the poet obsesses about their beloved, it is in the service of expressing their own true feelings. The feelings attach to the love object but originate from within.

One of the overarching arguments made in the poems is that true love is always the most important and powerful and can overcome not only status and class but also time and death. So much of the poetry speaks to it being read in the future. This is based on the idea that the truth of the love motivating the expression is stronger than the present moment.
