Vince Vaughn says being very shy when he was younger led to him making many "crazy" decisions.
The 'Delivery Man' actor - who has daughter Locklyn, three, and son Vernon, five months, with wife Kyla - hated how "scared" he always felt when he was a teenager, so behaved recklessly and got into fights, with his actions worrying teachers so much they urged him to see a psychiatrist.
Vince - who is 6ft 5in tall - said: "I wish I had not been so shy and scared as a kid. I did not want that feeling inside me -- so I made some crazy decisions. It made me drive a car when I was under-age, at 14, and I tried to do too many things which brought pressure on myself.
"I would cut school and challenge the teachers as I over-compensated for my shyness.
I was also a big boy and I would get into fights as I would be picked on. I was not the toughest kid, but if there was trouble I would be expected to sort it out because of my height.
"Teachers wanted me to see the school psychiatrist at one point because I didn't have the same type of academic pursuits as the other kids. I never went."
Despite his career success and global fame, Vince, 43, admits he is still shy and prefers to hide behind the characters he plays.
He added in an interview with The Sun newspaper: "I do not like the focus to be on me. I am much more comfortable playing a character rather than getting such personal attention. I am bashful and shy in that way."
