Dan Biggar knows that if he is averse to pressure and criticism then he needs to find a new career.
Because the man in ownership of the fabled Wales No.10 jersey has to deal with both, in spades.
Fortunately, though, the Northampton Saint has learned to cope with that pressure.
In fact, he thrives on it.
When Wales cruelly lost Leigh Halfpenny to a knee injury two weeks before the last World Cup, the wave of pressure washed over Biggar, who would take over the kicking duties for the tournament.
There were many who doubted whether he could hold his nerve at that level, suggesting the loss of Halfpenny’s deadly aim would cost Wales. Biggar went on to kicked imperiously all tournament, booting the winning penalty from halfway in the famous win over England.
More recently, in the wake of Wales losing Gareth Anscombe, again to a knee injury, the doubters returned. This time, legend JJ Williams proclaimed Wales couldn’t win a World Cup with Biggar steering the ship.
He went on to put in a man of the match performance just days later in the victory over England last month, and proceeded to with his tongue firmly planted in his cheek.
“I have had it my whole career,” Biggar tells WalesOnline. “There could be another ex-player calling for someone from Penclawdd to play No 10 next week! It’s one of things.
“If I’m not comfortable with that [criticism] in the position I play in this country, then I’m probably in the wrong job.
“It really doesn’t bother me. Everyone is entitled to their opinion, and I actually quite enjoy those things as it gives me motivation.
“It’s less about me, I couldn’t care less what he [Williams] said about me, it was more the negative comment about the team after one difficult afternoon.
“That’s gone. I haven’t thought about it since.”
But the 73-cap pivot wasn’t always so comfortable with criticism.
Even now, at the age of 29, he wears his heart on his sleeve out on the pitch and his emotions are always right on the edge.
And he admitted that, early in his career, the burden of that No.10 jersey weighed heavy not only on him, but those around him, also.
“Yes, definitely,” he nods, when asked if he has become better at dealing with the circus that surrounds the shirt.
“When you get a bit of a bumpy road the biggest thing is experience. You can’t coach or teach that. You have to be thrown in at the deep end and you have to have the character to shrug it off.
“Early on it was tough because it affected me and my family and friends. You don’t know how to take it because all of a sudden you’ve come from absolutely nowhere to being in the public eye and being criticised.
“My career has always been like that and in the position I’m in you have to expect it to be up and down. You’re never going to please everyone but I’m happy in myself and in life and the experience I’ve had playing in this shirt for nearly 10 years has served me very, very well.”
He added: “I’m fully aware everyone will have the person they prefer to play. For me I’ve always stuck to what I’ve done well in my career.
“I’ve been a competitor, kicked well, and been strong defensively. I’ve tried to work on everything else and hopefully we can get to the World Cup, score some tries, and play some running rugby as well.”
Any critical analysis that comes his way these days is almost immediately put into context.
Like so many sports stars who have a child, the arrival of Biggar’s son James has made him realise that there are more important things in life.
“That’s been a big thing for me over the last 12-18 months.”
The former Osprey, who was part of that 2013 tour of Japan that managed one victory and one defeat with the British and Irish Lions contingent taking care of business in Australia, is gearing up for his second Rugby World Cup.
And he’s looking forward to returning to the Land of the Rising Sun to get the full World Cup experience.
In 2015, Wales played all of their games in the Principality Stadium and Twickenham, two grounds they are very familiar with.
Japan is largely uncharted territory.
“I am really excited. The last World Cup was basically at the Principality Stadium and Twickenham, where we played our games,” he explained.
“We stayed at the Vale and the same place whenever we play England away so even though it was a great experience it didn’t feel like a real World Cup where you go to different grounds and stadiums and different places.
“This is more exciting and has a real World Cup feeling, going away, packing your bags and everything like that. Hopefully we can deliver on the big stage.”
Recalling the 2013 experience, he added: “It’s very different to Cardiff or Swansea. There’s not much English spoken. But having said that there’s not much English spoken in Swansea either!
“The language barrier is going to be difficult for everyone, but I am sure Japan are going to put on an amazing display. The infrastructure and everything they have got is going to be great.
“It’s something a few boys have done before and we will have to brush up on some Japanese phrases to get us round I think.”
Biggar, now acclimatising with the rest of the squad in Tokyo, is right to leave all the opinions and headlines in his rear-view mirror as the World Cup is almost upon us.
But does he believe Wales can win it all with him at 10?
“I hope so!” he laughs.
“That’s the plan. It could be Rhys Patchell at 10! The bottom line is, we have a tough pool – if we can get out of the pool first the other seven teams in the quarter finals will not want to play us.
“It’s about making sure we perform as well as we can, as we have done over the last 18 months, do the basics well and hopefully we’re in a good position to go on from there.”
