Matthew Mcconaughey doesn't think he's ''made it'' as an actor.

The 48-year-old Hollywood star might have had huge success in movies including 'Interstellar', 'The Wolf of Wall Street', and 'Dallas Buyers Club', but the actor isn't complacent when it comes to his fame and fortune, as he says admitting he's ''made it'' would make him ''stagnant''.

Speaking to BW magazine, he said: ''I don't believe that, 'Ah, I'm Matthew McConaughey. I'm 48, I've got a family, I've got a wife, I've got three kids, everyone's healthy right now, I've got a career, I've won an Oscar'. It's not like, 'Oh, I did it'.

''There's chapters of success and failures but there's not a spot where you get to take a deep breath and go - 'I've finally made it'. Then you become stagnant. That's not as fun.''

Matthew - who has children Levi, 10, Vida, eight, and Livingston, five, with his wife Camilla Alves - shot to fame after starring in 1993 hit movie 'Dazed and Confused', and went on to win a Best Actor Oscar for his performance as AIDS patient Ron Woodroof in 'Dallas Buyers Club'.

However, despite not thinking he's made it as an actor, the star did recently admit his breakout role in 'Dazed and Confused' transformed his life.

He said: ''That was the role that, at that time I didn't know if it was going to be a hobby or something I was doing for the summer, and it turned out to be a career.

''That's where it all started and I always look back to that one.''

Meanwhile, the 'True Detective' star heaped praise on his wife Camilla - whom he married in 2012 - for not wanting to change who he is.

When asked what he's most thankful for, he said: ''My life, three healthy children [and] my wife Camila who doesn't want to change me.''
