I take up my task in buoyancy and hope.

[Boris Tatarenko]

Hello.

At the end of Winston Churchill's speech "Blood, Sweat and Tears" he says: "I take up my task in buoyancy and hope. I feel sure that our cause will not be suffered to fail among men. I feel entitled at this juncture, at this time, to claim the aid of all and to say, "Come then, let us go forward together with our untied strength" ".

I don't think I translated the bold part correctly. Can you say to me what "take up" exactly means here?

Thanks in advance.
Boris.

It should mean just "take" (= I'm going to do it with buoyancy and hope). In Russian, it would sound as "берусь за".

Definition #1 here works

I've also heard the expression "to address oneself to (doing) something".
