The new Fine Gael leader has warned his party colleagues that there will be more disappointments than appointments when he selects his cabinet next week.
Leo Varadkar said that no decisions have been made yet but people will be selected based on their ability to deliver for the country.
He added that factors such as trust, as well as regional and gender balance will also influence his thinking.
Mr Varadkar, who is on course to be elected taoiseach in the Dáil next Wednesday, said he is thinking of restructuring some government departments to better reflect the needs of the country.
He described his meetings with Fianna Fáil and Independents yesterday as "fruitful".
On his meeting with Fianna Fáil leader Micheál Martin, Mr Vardakar said: "We're not going to be best friends but we're going to have a good working relationship."
He also said he did not know if there was any informal understanding between Independent TD Michael Lowry and Taoiseach Enda Kenny because he had not had any discussions with Mr Lowry yet.
Asked if he would honour such an understanding, he said it would depend on what it was.
But he insisted he would have enough votes to be elected taoiseach if Fianna Fáil abstain and the Independent Alliance along with Ministers Katherine Zappone and Denis Naughten vote for him.
Mr Vardakar also said he would consider a new approach to dealing with the Ibrahim Halawa case but added that he did not want to do anything that would be counter productive.
He said he welcomed the draft agreement on the new public service pay deal and was confident it would get the backing of Cabinet.
Mr Varadkar said he hoped to make contact tomorrow with the winner of the UK election to emphasise Ireland's views on Brexit.
