The 45-year-old left White Hart Lane on Tuesday, less than six months after he replaced Andre Villas-Boas in the dugout.
However, the experience has not put him off taking another position, and he told ITV4: "I really enjoyed it and I can't wait to get back in. Perversely I like doing it - to want to do that job you must be crazy.
"But I knew what I was going into. There's a lot of tension and pressure that occupies your mind totally. I was waking up in the night thinking of teams, who you should play.
"It was a massive learning curve, my first opportunity to manage.
"I've seen wins, defeats and draws and I've seen a few tantrums - and the sack, which I didn't want to see. Would I do anything different? Probably not."
Sherwood led Spurs to a sixth-placed finish and qualifying for next season's Europa League - however, speculation had surrounded his future in the role for several weeks.
On Wednesday's decision, he added: "Put it this way, I didn't fall off my chair when they told me. Obviously I was disappointed to lose my job."
Sherwood, already favourite for the vacant manager's post at Brighton, endured weeks of speculation on his future as he steered the team to Europa League qualification.
Despite a win rate of 59 per cent, that record proved to be not good enough for chairman Daniel Levy.
Former Spurs player Darren Anderton believes the club never thought of Sherwood as a long-term option and told Sky Sports News: "They gave him 18 months and there was a break clause and maybe this was the way (Levy) thought it would go.
"There was a World Cup coming up and the top managers were still involved in the Champions League.
"If Tim had got them into the top four then maybe he would have kept his job. Who knows?
"The team got into the Champions League two years ago under Harry Redknapp and once you're in it then you want it every year and that has to be the aim."
Sky Sports News revealed in early April that Sherwood was to be sacked at the end of the season and that Tottenham were actively pursuing his successor.
Weeks of reports linking other managers to White Hart Lane followed, including Holland coach Louis van Gaal, Ajax boss Frank de Boer and Southampton manager Mauricio Pochettino.
De Boer claimed over a fortnight ago that Tottenham had approached Ajax to inquire about his potential availability, while Pochettino has been made the favourite to take over by Sky Bet.
