Thomas, 34, is out of contract in the summer but wants to stay at the club until he's 37, citing the need to deliver genuine success to the Rodney Parade faithful as a motivating factor.
This term, the Dragons have won just four RaboDirect PRO12 matches - not helped by playing seven of their first matches away from home - and catching the Scarlets for a Heineken Cup spot appears an insurmountable task.
But Thomas is convinced that a new season will bring fresh optimism to Rodney Parade, claiming the Dragons are well placed to finish on a high, having won two of their last three matches.
"There's not that much we can look back on to be proud of, we can be going well one season then not do so well the next season," he said.
"It's down to a combination of things, and we've had a lot of those this season.
"There's pride for the team, for the jersey and as an individual. You love playing and you don't want to lose, that should always be there.
"It brings added pressure, but one good win can things turn around for us.
"I feel fit, well and healthy and I don't want to finish yet. I've got another three years left yet, no problem.
"I've only had one major injury (to his Achilles' tendon) and there are still parts of my game where I want to improve like the contact area and carrying the ball.
"It's a good place to play, it's nice playing for a living and rugby has been good to me."
