When things happen, they seem to happen all at the same time.
When things need to get done, they seem to need geting done all at the same time. When people need your attention, they all seem to want it at the same time.
What these have in common are the words 'seem', 'all' and 'time'. It 'seems' like you have to be an octopus or superhuman to be and do 'all at the same time'.
There are times when things and people really need your attention all at once and that's when you go crazy. But there are times when they only appear to require your attention simultaneously when in actual fact, some can wait. That's when you need to get a grip of the situation and prioritise.
