David Moyes has called for managers to be given time to implement their plans as he plots the way forward at Sunderland.
Moyes welcomes former club Everton to the Stadium of Light in Monday night's Premier League fixture.
The 53-year-old Scot spent 11 years at Goodison Park, where he established the Toffees in the top half of the table and took them into Europe despite working to relatively modest budgets.
Since leaving Everton, Moyes lasted less than a year as Manchester United manager before a 364-day spell in Spain as Real Sociedad boss.
And as he embarks upon his latest mission on Wearside, he insists it is no coincidence that managers who get the time to bring their plans to fruition enjoy the most success.
Moyes said: "You know, if you look at the clubs which really had good success, Brian Clough was at Nottingham Forest, I think, for 18 years; Sir Bobby Robson was at Ipswich Town for, I think, 13 years; Sir Alex Ferguson, you look at Arsene Wenger and then myself.
"If you look at the length of period that managers were there, you would say the clubs which have kept their manager for a long period have tended to get a level of success.
"They could be different eras, but because of media, because of a different type of pressure which comes under the owners or different owners I could say as well, it's not been quite so good.
"I was really fortunate that I worked under two great people in Sir Philip Carter and Bill Kenwright (at Everton). There were mistakes along the way, of course there were, and there were disappointments along the way, but they always saw the bigger picture and always had an idea where we were going."
Moyes understandably remembers his time at Everton fondly despite a shaky start to his reign.
He admitted: "I got lost on the way to the training ground the first morning, but it's a club I have got really fond memories of from the day I started.
"I remember the first game coming in and David Unsworth scoring a goal after 29 seconds, and taking the training, the level of players at that time.
"There was a very, very experienced group of players - there was still Paul Gascoigne, David Ginola, Duncan Ferguson, Tommy Gravesen, Alessandro Pistone, Davie Weir, Alan Stubbs, Kevin Campbell, Tomasz Radzinski - so we had a really, really strong senior group of players.
"But that had to evolve as well because I didn't like that this was a club which was only going to avoid relegation and thought that avoiding relegation was good enough."
