One way people commonly motivate themselves is by using fantasies about the future. The idea is that dreaming about a positive future helps motivate you towards that goal.
Beware, though, psychologists have found that fantasising about future success is actually bad for motivation. It seems that getting a taste of the future in the here and now reduces the drive to achieve it. Fantasies also fail to flag up the problems we’re likely to face on the way to our goals.
So what’s a better way to commit to goals? Instead of fantasising, use mental contrasting.
