with regards to imagination and creativity - nasa did an interesting bit of research, and it turns out 5 year olds are creative geniuses and adults have lost the way to be creative. However, teh good news is you can learn to tap into it again, you just need to practice.

The problem is as your grow up you're taught to learn through repetition and preparing for exams, you're castigated for daydreaming and you're not encouraged to "think" or imagine or be creative.
Now as a scientific person (I'm a chartered engineer) and someone who's quite pragmatic about stuff, I also lead on creative problem solving and innovation in a very uncreative sector (civil engineer / infrastructure) and there is a huge immaturity to creativity in adulthood. Only 2% of adults are truly creative - in problem solving we often use something call divergent thinking - allowing the mind to go crazy with weird and wonderful ideas etc... and then you use convergent tools to sharpen the focus and weed out the fantasy from reality. Honestly it's the most fascinating thing seeing a bunch of adults get completely sideswiped by asking them to imagine and think outside of the constraints of their day job. Through the work that the company I run we've been able to uncover multi £bn of opportunities ( of course opportunities dont' turn to value unless they're implemented) - but the "belief" about creativity in a pragmatic/scientific field is starting to be seen - however people default back to what they're comfortable with.
I'm a massive day dreamer, especially if I go for a walk, or commuting, my mind will wander as well as sometimes in the wee hours of the morning, that's why I keep a notepad by my bed to scribble down my mad thoughts.
You can learn to unlock your imagination but you've got to work at it, and it's still not a natural skill for a lot of people - and often the pale male and stale leadership don't want to hear about this "weird" stuff - all they want is P&L, ROI, KPIs etc... but I push back against all of that and purposefully disrupt the board because I don't believe that that alone will deliver the best opportunities.
A question, when you read a book (fiction) do you imagine the scenes and events that are happening or do you find it hard to visualise?
