Strachan, 52, set his sights on inspiring his team to promotion from the Championship when he was paraded before the media at Boro's Riverside Stadium after taking over the helm following Gareth Southgate's sacking.
The former Celtic manager said: "It's a special job. I don't have to be here, I don't need to be here, I want to be here. I don't need football but when I'm in it, I love it.

"My job is to make the players better technically, physically and mentally, as a group and as individuals.
"I've got some ideas for training and we'll develop that through the week and try to put it into practice at the weekend."
Strachan has already sounded out members of his scouting staff including his former team-mate, Boro's chief European scout Gordon McQueen, with a view to strengthening his squad.
"We've got a couple of strikers injured, so we'll try to develop that area in one way or another," he said.
Chief executive Keith Lamb said first spoke to Strachan about the possibility of him returning to management after Boro's game at Coventry City, but he insisted nothing was agreed until after Gareth Southgate left the club.
"One of the things that attracted him here was he has a bunch of players who need help and assistance," said Lamb who runs the club for Boro owner Steve Gibson
"We feel we need an experienced hand on the tiller. It will be fun working with him and he brings a bit of personality and sunshine."
Boro are currently fourth in the Championship table and Strachan's first game in charge will be against Paul Sturrock's Plymouth Argyle on Saturday at the Riverside.
