The striker had a bright start to life at the south Wales side, scoring five times in the opening two months of the season. Abraham went on to make his senior debut for England - snubbing the overtures of Nigeria - against Germany and Brazil in November.
However, the goals have dried up since October and the Chelsea loanee is yet to start an English Premier League match since December 30.
And Carvalhal wants Abraham to avoid the distractions that come with being a professional footballer, urging the striker to imbibe the discipline of the five-time Ballon d'Or winner.
"When a boy has the talent to be a top player there is one path to take, and if they have principles and dedication they achieve a top level," Carvalhal was quoted as saying by Sky Sports.
"I know in a lot of cases there have been players with a lot of talent at 19, 20 or 21 years old who have promised a lot, but lose the path and never become big players.
"Some of them had more talent than the big players of the world. Look at Cristiano Ronaldo. You can see him now at 32, but at 21 or 22 you never saw him involved in a fight at a discotheque, or with problems.
"This is very difficult as you win a lot of money at 20, 21, 22 years old. You are rich, but he continues to be the same guy, with the same work and attitude and it is down to the principles of the family and club.
"Other guys in the same situation lose that path. They want to enjoy the life, the nightlife and they lose their way.
"All these things come down to who you are and what you have in your head."
Wilfried Bony's season-ending injury has pushed Abraham up the strikers' pecking order at the Liberty Stadium outfit.
And the former Bristol City player is set for his first start in over two months in Tuesday's FA Cup fourth-round replay against Notts County, thus, presenting him another chance to recapture his early season form.
"I have spoken to Abraham and he knows exactly what he must do to be part of the team and a more complete player," Carvalhal continues.
"He has a challenge in hand to show he is progressing in the main points I have talked about with him, and I am curious to see the reaction.
"If he does what we want he will be a better player, so let's see what happens. We believe we can progress him as a player."
