But the truth is that ‘right’ doesn’t really exist. As Dr Hibberd reminds me, “‘Perfect’ gives the illusion that there’s a right choice, but actually there are many ways of doing things. If there’s a right choice, it also means there is a wrong choice and this can be paralysing.

You can feel like it’s your responsibility to get it right and that you’re at fault if you get it wrong. You can’t be completely in control of life!” And – adventures in quantum mechanics notwithstanding – you will never know how the other timeline would have turned out. All that exists is the choice you made, and the way you respond to it afterwards.

Meanwhile, learning to settle for imperfection could be the answer to all our indecisive woes. Back in 1956, economist Herbert A. Simon suggested the happiest people in life are “satisficers” – those who look for an option that’s ‘good enough’, rather than “maximisers” (hiya) who strive for the very best in everything and inevitably crack under the pressure. It makes sense, let’s be honest. Yet more than half a century later, we’re still struggling to learn how to settle.

So how does a maximiser become a satisficer? “Remember, mistakes, failures and ‘wrong’ choices are not the end of the world. They are part of the process of learning and finding the right way. They also build resilience,” says Dr Hibberd. She recommends allocating the time you spend on a decision in proportion to its actual importance. “Ask yourself: ‘will this matter in a day, a week, a year, five years?’ and give your time accordingly.”

We find it harder than ever to make decisions in 2018 - but why?
