Harrington has a CV in the game to make the majority of his competitors at Dundonald Links envious, and that's something he's grown to accept and appreciate.
Rather than heap pressure on himself to win every event he enters and become frustrated if he doesn't, the former European number one instead chooses to go easy on himself.
His relaxed attitude to competition is clearly paying dividends, with the 45-year-old very much in contention at the Scottish Open, his flawless -4 second round building on a -5 score on Thursday and helping him surge into an early lead.
"When I was coming through I could see players fighting it and I would ask them why," said the likable Dubliner.
