The Vikings are top of the table with five wins from their opening six games and next face Wigan on Thursday.
"You've got to be on your game and the lads and coaches are working hard to prepare and are reviewing how we can get better," Betts said.
"It's how we train and carry ourselves, those things don't just turn up."
Since regaining their Super League license in 2012, Widnes have failed to finish in the top half of the table.
Last season they went through the Qualifiers to retain their top-flight status, but Betts says they are better equipped to succeed this season.
"Working hard and making it happen week in week out, that's a skill and it's something that we've not been able to do throughout the last three years," Betts told BBC Radio Merseyside.
"We've got some distinctive, confident players so we've scored some points and passed the ball really well and asked some questions."

After Widnes thrashed Hull FC 46-6 last week, Betts admits he is finding it difficult to rotate his squad with his side performing so well.
"The tough thing at the moment is we've got three or four lads who you want to try and give some game time to, like Paddy Flynn, Pat Ah Van and Tom Gilmore," he added.
"It's hard to get Tom into the game and I know I'm going to have to use him. I need him fit and need him to get some game time, but it's hard when the half-back pair is playing as well as it is."

The Serb, 27, won 6-2 6-2 to extend his unbeaten run indoors to 30 matches stretching back to 2012.
He tops Group A in London with three wins and will play Kei Nishikori in the semi-finals on Saturday.
Stan Wawrinka will play Roger Federer in the second semi as he won the three games required against Marin Cilic.
Wawrinka, the Australian Open champion, took only 13 minutes to move 3-1 ahead and so ensure he could not be overtaken by Cilic in any of the qualification scenarios.
The Swiss number two went on to win 6-3 4-6 6-3 and return to the last four after his debut appearance 12 months ago.

Czech player Berdych, 29, suffered a 17th defeat in 19 matches against Djokovic but made more of a mark than in their last meeting, when he trailed 6-0 5-0 in Beijing last month before grabbing two games.
A similar drubbing appeared on the cards when the Serb raced into a 4-0 lead with two breaks of serve.
After a week of one-sided matches at the O2 Arena there was relief all around when Berdych recovered from 15-30 to get on the scoreboard in game five, but it was hardly a signal of intent.
Djokovic continued to dominate, rolling through the first set in 31 minutes and making it five games in a row as he moved 4-0 clear in the second.
Berdych slowed the two-time champion's progress sufficiently to take him past the hour mark, but Djokovic sealed victory after 69 minutes, and with it the end-of-season number one ranking for the third time in his career.
"Definitely one of the best," Djokovic said of his performance. "Obviously I hoped I could continue the way I played in the first two matches.
"It's been a long year, a long season, it's an incredible achievement and I want to thank my team and my family and all the people who supported me.
"I'm aware that being number one in the world is the biggest challenge a tennis player can have. It's an incredible feeling and I'm very happy."
Meanwhile, Wawrinka was left to look ahead to Saturday's second semi-final where he will face compatriot Federer.
"I hope I can get a little bit of support because I know people love him here. It's going to be tough for me, but I need to trust myself and go for it," said Wawrinka.
"It was a tough match tonight, it's never easy to play against Marin, he's been having an amazing year. It was not easy, trying to be aggressive. I was trying to serve and volley."
Widnes Vikings boss Denis Betts says their strong start to the Super League season is a reflection of their meticulous work in training.
