Help with english to latin

Hello!
I would like to translate the following sentence to correct latin.
I've been having real problems with this one because of the verb form.
the sentence is "never give up"

I'm very keen on using the correct verb for "give up" and NOT "surrender"

The reason I've been have trouble is because I'm not sure of wich verb I should use, or to use denying imperative form och gerundivum or something else!

the suggestions I've gotten so far are:
noli te dedere
spes/conatus numquam abicienda/i
nunquam redono


Edit:I might add that the phrase is referring to myself, as in "life's hard but (I will/should) never give up"


(please excuse any english language barriers, for english is not my native tounge

Thank you.
