Loneliness is necessary for pure poetry. When someone intrudes into the poet's life (and any sudden personal contact, whether in the bed or in the heart, is an intrusion) the poet loses his or her balance for a moment, slips into being what he or she is, uses his or her poetry as one would use money or sympathy. The person who writes the poetry emerges, tentatively, like a hermit crab from a conch shell. The poet, for that instant, ceases to be a dead person.
My first advice would be to read, read, read, which sounds interesting coming in a digital age, but it's so much easier to listen to a poem than it is to sit down and actually read it and to hear it in your head and that is something that every poet or aspiring poet needs to be able to do, I think to hear it in their head.
