Ok. I humbly accept my mistake while writing "no matter who "small" the task is". It should rather have been "no matter how "small" the task is".
Also, just to let you know you yourself made a mistake in "Your definition of carefulness, world leader, big difference, prefectionist is amazing!"
And could you please define the terms carefulness, world leader, big difference and prefectionist, if you think they're wrong ? Or point out if they're wrong in the context in which I have used them ?
