Simply put:
All Jews, men, women and even children, have the responsibility to increase their efforts to bring our righteous Moshiach in actual reality!
Therefore it's obvious there's no place for relying on others or imposing the work on someone else instead of doing it one's self - but this is the task of every man and woman; everyone must themselves do their job, "to serve my Maker" (for the sake of which "I was created"), and certainly one has the ability (since "I do not ask except according to their ability").
What this duty consists of is also simple: increasing one's Torah and mitzvos. This means learning both the open aspects of the Torah and the inner aspects of the Torah and performing the mitzvos with distinction... All of this should be done with an intense anticipation and desire for the Redemption - "I anxiously await his coming every day."
As we say every day in the prayers: "May our eyes behold Your return to Zion in mercy" and (on weekdays) - "Speedily cause the scion of David Your servant to flourish." This has been mentioned many times.
