The 23-year-old made his debut for Wales off the bench against Canada in 2008 and was used as a replacement in four of his next eight appearances for the nation.
Only since the start of this year's RBS 6 Nations has Biggar been a regular starter for Wales, helping them bounce back from defeat to Ireland to down France and then Italy.
And, despite following in the footsteps of Wales greats like Jonathan Davies and Stephen Jones, Biggar is determined not to dwell on where he finds himself.
"I'm just enjoying being part of the set-up," said Biggar. "Of course there's pressure but I try to deal with it and the wins we have had over France and Italy have been great to be a part of.
"I don't think it's helpful for me to get caught up in any hype over the jersey. I know there is a lot of tradition attached to the fly-half position in Wales.
"But as a group we cherish every jersey, whether it's the No.10 or the No.4 shirt. There are pressures at No.10 but there are pressures in every position.
"You just try to make the most of playing for Wales and do your best. You have to take the rough with the smooth.
"When your pack is going well and the team is winning, it becomes easier for a fly-half and everyone is happy.
"When the forwards are on the back foot and the fly-half's life is tougher, everyone is more critical. I don't have complaints about that."
"Sport, like life, isn't a straight line. There are ups and downs and there can't be anyone who has played the game who would disagree with that."
