What is the origins of the considerata poem?

I think you mean the Desiderata.

Wikipedia, in a largely unreferenced article, states:

Desiderata (Latin for "desired things", plural of desideratum) is a prose poem by Max Ehrmann about attaining happiness in life. It begins: "Go placidly amid the noise and haste, and remember what peace there may be in silence."

It is said to have been written in 1927. The language is certainly not as old as the date ascribed to its discovery in St Paul's Church, Baltimore. That date, 1692, is the year the church was founded.

Since the current owner of the Desiderata's copyright is a vigorous pursuer of those who breach it, there may very well be peace in silence. Avoid loud and aggressive persons; they are vexatious to the spirit.
