Everyone knows the secret to success. Start young, find something you love, and then work hard without changing course. Right?

When you look at the careers of successful people, it is easy to get that impression. Just think of Taylor Swift, Emma Raducanu, or Leonardo DiCaprio.

However, plenty of people take an indirect route to success.

In the Middle Ages, most self-help books were written by monks and nuns. Known as medieval mystics, they explained religion in terms of emotion and spiritual wisdom, and understood the need for flexibility.

Meister Eckhart, a mystical writer from 13th Century Germany, wrote that people should "live without a why". He did not mean living without purpose, but without investing your self-worth in one single achievement. Modern science agrees and warns against thinking that achieving a next goal - be it a job, a house, finding a partner - will finally make them happy.

Instead, keep your options open. You will change, jobs will change, and the world will change.

But psychologist Heidi Grant warns that keeping your options open leads to less happiness and success, because if people can reverse a decision, they are more likely to worry that they have made a mistake.

The employment landscape is changing. Two-thirds of the fastest growing professions were invented in the past 20 years - from AI engineers to environmental consultants.

Having plans and goals makes us happy, but it is important to revisit them often.

Is it okay to be unsure?

Yes! Nobody knows what the employment market will look like in a decade. The more flexible people are, the more they can change direction as the world around them changes too.

No! Keeping options open either means you are less likely to make a decision, or more likely to regret that decision. If you commit to one thing, your brain begins to believe you have made the right choice.
