Scrum-half Sam Hidalgo-Clyne says he is fulfilling a lifetime dream by being part of Scotland's World Cup squad.
Having only played professionally with Edinburgh since the summer of 2012, he made his international debut earlier this year in the Six Nations defeat by France.
"Just turning 22 and going to a World Cup for me is a great honour," Hidalgo-Clyne told BBC Scotland.
"The experience is going to be the biggest thing."
Scotland open their Pool B campaign against Japan before facing USA, Samoa and group favourites South Africa.
"As a youngster I always looked to gain as much as experience as possible and try to have a wise head on young shoulders," Hidalgo-Clyne explained.
"Learning from [fellow half-back] Greg [Laidlaw] over the past wee while has been great and I'm enjoying it as much as I can.
"For us we just need to look at the pool stage first. The first two games, you can't put them past you.
"Japan have had a big run of games and they have got a very good dominant set piece. Ours hasn't been hugely dominant in the past four games so if we get that area right against the USA as well, who are a physical team, then we can maybe look past to the Samoa game and the South Africans."
Outside of Scotland's pool Hidalgo-Clyne says he expects Ireland to make a major impression on the tournament.
"They have been together for a long time and they know each other very well, and are always a good team at a World Cup, so on their day they can perform really well," Hidalgo-Clyne added.
"I think there is a lot of pressure on the All Blacks. On paper they are the best team in the World.
"They have a good game plan and their basic skills are probably the best in the world which is probably why they win a lot of games."
