Prayers, praise, and political advice were sent the Taoiseach's way in the days after he returned to the top job in Government last December.
Three dozen emails and letters were penned by members of the public to the new Taoiseach, according to documents released following a Freedom of Information request.
One writer strongly urged Leo Varadkar to remind the Green Party that "they represent a minuscule (part) of the Irish electorate".
They told Mr Varadkar that "enough is enough with the Green agenda. Fine Gael needs to reflect the views of those who elected them and not be led by a minority party".
However, others emphasised the importance of maintaining a close working relationship with the two other parties in Government.
"Keep the three leaders group close and build momentum on the key issues," one person wrote, and they advised Mr Varadkar that there was "lots of work to do...to achieve things in Government and to convince the people to keep you".
There were also suggestions that the Taoiseach should build relationships with international leaders and to look again to his friendship with Canadian Prime Minister Justin Trudeau.
There was praise too for the smooth change-over within the Office of Taoiseach on 17 December, with one email from that day stating: "No problem at all with Micheál Martin, but it's good to see Ireland's democratic process working exactly as it should."
There was a promise of prayers for the Taoiseach's "health, prosperity and happiness," and he was asked to promote "Divine Mercy Jesus".
This was followed with advice to remain humble, with one writer on New Year's Day telling Mr Varadkar to "never to be smug, it's not worth it".
Others praised the Taoiseach's "fresh and proactive approach to policy," but one writer lamented the lack of "creative purpose" at leadership level in the country.
The Taoiseach was also told that if someone stands to gain financially from the advice they are offering him, then he should "filter that advice with a very fine sieve".
One person who welcomed Leo Varadkar back to the "hot seat" predicted it was likely to be "hotter than ever over the next two to three years".
They wrote about the need for "massive infrastructure, new bridges, schools, buses, more doctors," before adding that "we have prefab schools, too much talk, too many reports, (and) little or no real action".
One New Year's Eve, an email writer, taking a more sanguine view of matters, asked the Taoiseach to remind people that "we live in a country that is safe, democratic and beautiful".
In his second term as Taoiseach, Mr Varadkar was advised in another email not to let all the "hate online" from "young people who seem to identify as communists" get to him and to keep his "chin up".
A woman who described herself as "very elderly" emailed Mr Varadkar to tell him she had heard him spoken of in glowing terms by "two burly 40-something-year-old taxi drivers" with "strong accents".
Others though were less acquainted with the rotating Taoiseach concept it seems, with one email correspondent on 5 January simply stating: "Leo, I see you have returned. What happened to Martin?"
