It's goot to have targets but we should not be too much attached to them. I like doing my best to achieve them, planning every single detail but sometimes, things simply have to go in another way meaning that maybe it was not time for me to get some kind of achievement.
Still, there is plenty to learn for the next target :D
The attachment is where suffering lays. Having targets is good, but understanding that things change and targets might need to be redefined has to be considered.
