Paul di Resta's manager expects the Force India rookie to become more articulate as his Formula One career progresses.
Observers have been impressed with the 25-year-old's on-track antics so far in 2011 but less so with his low profile and robotic appearances for the media.
But while acknowledging di Resta's unremarkable paddock presence, his manager Anthony Hamilton said he expects the Scot to raise his head once his future is more secure.
Di Resta is in the running to keep his seat at Force India next year, but so too are his current teammate Adrian Sutil as well as Friday driver Nico Hulkenberg.
"I'm extremely proud of Paul, he's so level-headed," said Hamilton, the father of the 2008 world champion and McLaren driver Lewis.
"Yes, he (di Resta) is quiet, but it's what you do on the track that's most important. That's what is most important for keeping your job in F1," he told the Independent.
The key for him is to say little, but deliver big
"There is the constant threat of other drivers with huge budgets, so a driver who is in a team on merit, such as Paul, can lose his seat if he says the wrong things or doesn't perform. The key for him is to say little, but deliver big.
"Once you have established more of a long-term career you can open yourself up a little more. Right now, Paul is in that position where you just have to keep yourself to yourself, keep your head down, and do the job on the track," added Hamilton Snr.
