If you were required to finish multiple tasks by the end of the day & there was no conceivable way that you could finish them?

well, better have good planning and organizing the tasks. organize and plan the tomorrows task today. make a priority of the task and keep flaoting the tasks buckets accordingly. do not procastinate and be very true to yourself. have patience as every task has its own importance and natural flow of completeness, understand that flow and try to mitigate the gaps for smooth finishing and time saving

hope this shold help
