The 21-year-old has ramped up his Premier League goal output in 2018-19, netting 12 in 29 appearances for the Toffees compared to five in 38 for Watford last season.
"Marco Silva is always talking to me in training, he is always giving me guidance on positioning in the area," Richarlison told Everton's official club website.
"His coaching is essential for me. He is training me with an eye to being in the right place at the right time when balls come into the box, so I am able to score more goals.
"I feel I have been developing more and more. I want to show I can play at my best for a whole Premier League season. I feel really good at Everton. My team-mates are helping me with my confidence on the field and that is vital.
"And being part of the Brazil national team has been really important for my morale and a positive thing for my confidence."
Richarlison said he understood why Silva opted to utilise him from the substitutes' bench in Everton's recent games against Manchester City and Liverpool, before he was restored to the starting line-up against Newcastle United and Chelsea.
Silva's men are 11th in the Premier League table after losing only one of their last four matches, and Richarlison says rotation was important to the club's hopes of finishing in the top half.
"It is an incredibly intense season, right from the start, and he [Silva] needed to protect me a bit," he said, reflecting on his time outside the starting XI.
"I understood that completely. My team-mates also have to be given a chance.
"But I will always work really hard in the week and hope it ends with me with me playing in the team."
Everton's next fixture is against West Ham on March 30.
