Fired Apprentice candidate Tim Stillwell revealed the one thing he has learned from being on the show is to know when to keep his mouth shut.
The 23-year-old Mexican food entrepreneur drew attention to himself at the end of the first task by launching into a speech about how Lord Sugar had not seen the best of him, despite his team having already been declared the winners and dismissed from the boardroom.
In the second task, Lord Sugar delegated Stillwell the position of project manager of the girls' team Evolve to give him a chance to live up to his promise.
Tasked with creating and a selling a flavoured beer, Evolve lost by making the least profit after choosing to sell their product at a local beer festival that turned out to be based in a small pub.
Stillwell admitted he regretted speaking up at the end of the first task "big time".
He said: "The best thing that I've learned is that there's a time when you don't need to talk. There's a time to speak up, and there's a time when you should just let it go."
But the Birmingham businessman confessed he could not resist trying to have the last word in the boardroom.
He said: "It's sort of like when you're having an argument with somebody and they cut you off, and even though the argument's over you still have so much to say about it.
"But usually you don't have eight cameras on you and loads of eyes, so you can calm down and think I'll just drop it. But I was unprepared to drop my argument with Lord Sugar.
"In reality I should have kept calm and just left it and thought I'll prove myself in the next task. But he put me in my place quite quickly."
