"SMART" goals (specific, measurable, achievable, realistic & time bound) don't always work! 

• They focus on outcomes vs. the behaviors needed to achieve great outcomes... 
• ...you may get the outcome you want without meaningful behavioral change 
• Most situations are very fluid, so what's "achievable" & "realistic" is constantly changing...
• ...if the changing environment makes your goal less achievable or realistic people get very demotivated
• If the changing environment makes your goal easier, people tend to back off and coast 
• SMART goals encourage pursuing outcomes that you're already equipped to handle
