Being able to do two things at once might seem like the epitome of efficiency – why waste time doing just one task when you can complete two simultaneously?
However, famously there is a belief (myth?) that women can mulitask but men cannot – hampered by having a ‘one track mind’.
In the real world, rather than the world of gender politics, multitasking seems to be unfruitful, since in practice the work style is not multitasking but micro-sequencing of two parallel tasks. The problem is that the brain switches so often between the two tasks and focus is lost on each switch and there is a delay each time the switch occurs.
So, stick to one task, focus and concentrate, complete it – and then move on to the next task. You will be more productive.
