This is the era of the gadgets and applications, so I think we must make use of them for our benefit, gone were the days when you had to plan the activities after every hour or day because today, we can plan the work of the whole week in just one day which is good because by this way you do not loose your concentrations. Just set the alarms and reminders at different timings and divide your work between those alarms, because by that you can focus on that specific work either its money or job.
