WHY WE MAKE PLANS, BUT DON'T TAKE ACTION
One explanation for why akrasia rules our lives and procrastination pulls us in has to do with a behavioral economics term called “time inconsistency.” Time inconsistency refers to the tendency of the human brain to value immediate rewards more highly than future rewards.
When you make plans for yourself — like setting a goal to lose weight or write a book or learn a language — you are actually making plans for your future self. You are envisioning what you want your life to be like in the future and when you think about the future it is easy for your brain to see the value in taking actions with long-term benefits.
When the time comes to make a decision, however, you are no longer making a choice for your future self. Now you are in the moment and your brain is thinking about the present self. And researchers have discovered that the present self really likes instant gratification, not long-term payoff. This is one reason why you might go to bed feeling motivated to make a change in your life, but when you wake up you find yourself falling into old patterns. Your brain values long-term benefits when they are in the future, but it values immediate gratification when it comes to the present moment.
This is one reason why the ability to delay gratification is such a great predictor of success in life. Understanding how to resist the pull of instant gratification—at least occasionally, if not consistently—can help you bridge the gap between where you are and where you want to be.
