What does this stanza from a poem mean?

It would have helped if you wrote the name and the author of poem. The poem is A Short Song of Congratulation by Samuel Johnson. I once read almost every single work by Dr.Johnson... anyway this poem is a bit satirical and ironic, funny, congratulatory poem on the twenty-first birthday (the coming-of-age year) of a young heir, Sir John Lade. In the poem, Johnson satirizes the spirit of carpe diem (enjoy whenever you can) held by most people of this age. In particular, Johnson satirizes the way that young squire’s often forget their larger responsibilities to their families and their communities. It basically portrays Johnson as the indulgent, lenient uncle who gives his a fun advice unlike his strict parents. Johnson basically tells his nephew to spend his money on gambling, whoring and all of the other pastimes typical of a beau of his age and advices him not to listen to the old farts' "counsel and their pother" because he can always commit suicide when things get tough. It is also possible that Johnson wanted to live his life as his young nephew.
