Earlier this month the 25-year-old penned a two-year deal with the Irish province, tying him down until 2017.
And after progressing through Munster's academy to gain his first European start in January, O'Mahony acknowledges he has never lacked the motivation to succeed.
"Training hard, doing a lot of extras, and trying to get consistent performances is key. You want to play for your team mates, your family and your coaches," he told the club website.
"You want to put your best foot forward every weekend. Lucky enough I've gotten the opportunity to wear the jersey a lot this season and I'm very grateful for that.
"I want to keep pushing forward and keep striding to be better."
O'Mahony burst onto the scene after making a try-scoring debut against Newport Gwent Dragons at Rodney Parade in April 2013.
The Irish winger's most recent appearance came in Munster's Round 14 GUINNESS PRO12 match against Cardiff Blues when he scored a late try to seal a 33-16 victory over the Welsh side.
Next up for Munster is the weekend's important clash against league leaders Glasgow Warriors and O'Mahony insists his side must seize this opportunity to cement their place near the summit of the GUINNESS PRO12.
"Glasgow are in our way now this weekend and we want to put our best foot forward and go out there and put in a good performance and get a win," he added.
"They've a great continuity game, they don't get tied into mini rucks, they've a huge amount of lads that can offload on the team, they're constantly dangerous with quick taps, and they've a lot of variations off line outs and a good set piece.
"We'll have to look after that, stay awake in defence, be alive for everything and get a performance at the end of it."
