It has always been 24 hours for a given day since time immemorial.
Given that, it is ridiculous to use 'I don't have enough time' as an excuse for not getting something done. It is always priority which dictates what we do and what we don't and not time. No wonder why we manage to watch all the good movies but might not have set the right priorities for life (and crib about it) or easily ensure that our inventory is loaded with enough of our favorite snacks but never manage to exercise.
If you still have your doubts then answer this – Will you ever say that you don't have time to swim when in the middle of the ocean?
