My point was that in FP you build things by composing existing things which require much more thinking it terms of trying different permutation and combinations at which the right brain is much more capable of. In general when I am doing FP I need to do lot of thinking and it requires some time whereas in imperative programming you can basically start coding as soon as you heard the problem. Ofcourse in the end the FP solution is much more elegant and simple
