We've all done it. Written out a to-do list at the start of the day and then, wen we write out out list the next just added every thing back onto it.
If the things on your to-do list are not too important and don't have to be completed by a set time, then this isn't such a big thing however, when you really need to get something done it starts to become more critical.
So, SMART targets are the way to go forward.
Setting SMART targets make you revisit what you've set out to do and check if you can actually achieve it by using a simple check list:
S - Specific
M - Measurable
A - Achievable
R - Realistic
T - Timebound
