What is a summery of digging by Seamus Heaney?

it is about his emotions to the fact that Seamus Heaney will not continue the family Farming tradition. At first he is upset but then he gradually starts to explain how farming was so important to his family. Then He realises and starts to appreciate how his talent is to write and he is glad about it.

In my hand the squat pen rests... I will dig with it... :)
