I prioritize my tasks based on the level of importance, the urgency that the task needs to get done, the effort, and the time taken for those tasks. I would of course start with the important and urgent tasks, and if a task is short and important I would probably get, if there was multiple short important tasks, I would probably knock all those out first before I move on to a bigger time consuming task. But any less important tasks would come after the important urgent ones, especially if they take a longer time and more effort to do them. But those important tasks would always get done in the end.
