An ex-pupil of Seafield Convent grammar school in Crosby where she was described as a "truly exceptionally clever child", Mrs Blair, 49, is proud of her achievements as a lawyer and as a mother.
"I count myself extremely lucky to have a fantastic family and the career I always wanted."
Last night she was in Liverpool to host a banquet at a top city Chinese restaurant to raise funds for the homeless charity Emmaus.
Guests paid £1,000 a head to hear her speech, with all the money going to Emmaus which is looking to build a £1.5m hostel for the homeless in Liverpool.
Speaking at the Devonshire Hotel where she was staying prior to the event, Mrs Blair revealed she has supported the homeless charity for almost a decade.
She said: "I became interested in the work of Emmaus before Tony became prime minister.
"What I really like about the charity is it aims to give homeless people an independent life, and it allows them to work for a living and get their self-respect.
"Anything that gives people a sense of self-worth has to be good."
Emmaus volunteers are looking to build their sixth hostel in the UK and it would house between 25 and 30 people.
Mrs Blair was today completing her engagements on Merseyside with a visit to Lyndale School in Eastham where she will offically open a new sensory garden.
