Aguilar claimed his UFC deal by submitting Da Silva with a strong guillotine choke in the third round of their flyweight battle on Tuesday.
An excited Aguilar, who is now 8-1, told the press after the fight that it was his unwavering determination which gave him the edge against a formidable opponent.
"Very well prepared from my team, they talk about the mentality. That's a very important thing," Aguilar told reporters, as quoted by MMA Junkie.
"I understand that he's a good fighter, I've watched his fights before, but this is a team effort, and it didn't just happen.
"It was a fruit of our work, and I want it more, and I want it for my family, and that's why it happened."
It's not yet clear who Aguilar will fight in his UFC debut, but he is eager to get back into the gym to work on his game before thinking about his next fight.
"I want to fight when my coach says I'm ready to go," he continued.
"I would like to fine tune a couple of things. I would like to maybe give it to December and stay with the family, so I will be completely focused on the fight at hand, but you know what, my coach has this covered."
