Alan Pardew has turned things around following a testing spell as Newcastle United manager, where supporters were quick to criticise him.
Sherwood is under a huge amount of pressure after Villa's poor start to the season, but the 46-year-old has seen how quickly things can turn around in football.
Pardew has gone from being in a job at Newcastle United where he was constantly criticised by the supporters, to being flavour of the month at Palace.
And Sherwood said: "I look up to managers who have stood up in tough periods. I take inspiration from Alan Pardew. He's now favourite for the England job when Roy [Hodgson] leaves. A real turnaround.
"I take a lot of heart from managers who have been through difficult periods. This is my first tough period in management. We'll soldier on and get through it. I have 100 per cent belief that we'll stay in the Premier League."
There have been reports in the Daily Mirror recently suggesting that Sherwood only has two games left in which to save his job at Villa.
The Claret and Blues take on Chelsea and Swansea City in their next two matches, and they will be desperate to get some points on board.
Villa have not won since the first day of the 2015/16 Premier League season, and they are already having to play catch-up.
Sherwood's side are four points adrift of safety as things stand, and he will realise that their poor form cannot continue for much longer if he wants to remain in work.
