Cleverly says the belief of pundits such as Barry McGuigan and Duke McKenzie in his potential to emulate some of Joe Calzaghe's success is also a boost.
He added: "There are a lot of people talking now, a lot of experts like Barry McGuigan, Duke Mckenzie - yeah, and even Joe himself - they all think I've got the potential to go all the way.
"But I don't want to get carried away with those statements and think I've cracked it because there's still a lot of work to be done.
"That [beating McIntosh] was a major stepping stone for me. The Commonwealth belt was a good stepping stone and to pick up the British as well, that's a major step again.
"I've got the Commonwealth belt and the British belt and it's all at 22 years of age so there's a lot of potential, a lot of maturing in me yet and there are a lot of big fights to come.
"I'm looking to go all the way and I want a legacy of my own to fulfil.
"This has been a major stepping stone for me."
Cleverly disposed of McIntosh in seven rounds to remain undefeated in his 17 fights.
He added: "I go into the boxing ring without a game plan. To be honest, I normally box on my instincts.
"But before this fight I said 'I'm going to go in, I'm going to put him on the back foot because I know he likes to bully an opponent' so I thought I'll put him on the back foot and that's what I did straight from the start."
