The 46-year-old actress - who has been married twice, to Spandau Ballet star Gary Kemp and actor Jude Law - has curbed the desire to react to a situation quickly because she has concluded it is best to see "the bigger picture".
She said "What have I learned about love? Not to be impulsive. I think that sometimes you make decisions in the now and don`t realise the effect they`re going to have on your whole life.
"When it comes to relationships, it`s much better to see the big picture."
However, Sadie - who has four children from her marriages - continues to be single, something she is not pleased with as she misses the intimacy that comes from being in a relationship.
She added: "I`d love to be in a relationship. Someone to cook me breakfast and tickle my toes.
"That`s what I miss; the little things. I feel I am in such a good place. I should be sharing this with someone."
