Goals can be very good if created responsibly.
For instance, assume two equally skilled and equally bankrolled players set out to win PCA seats.
Players A plays when he feels up to it, and knows he wants to win a seat and not much else.
Player B organizes the task into a series of smaller objectives, for instance:
1) win 650 W$ by playing rebuy sats
2) Sweat the end of the Saturday MTT to have a general idea of what to expect toward the bubble.
3) Play the MTT sat on Nov 26th at the very earliest, assuming I've earned XXX $ by then, if not defer to two weeks later.
Setting goals like 'FT 6 tournaments' or 'win 5' is arbitrary and counter to the nature of MTTs, I agree with you there but certain calendar-based goals can be useful and I may go so far as to say necessary to maximizing your game.
There are a lot of goals (i.e. re-read TOP next week, finish that post I've been working on re: Stars 500k data*, play 5 deepstack tournaments this month to prepare for the WPT in January, ...), which I would argue are absolutely necessary to making one the best player they can be.
It is quite easy for a good player to get stuck in a groove and not better his game if he has not set goals to challenge himself to improve.

P.S.
No offense, but after a period, the next letter should be in what's called "upper case", for instance 'a' becomes 'A' and so on, otherwise reading your posts is a major headache.
Read up and correct this in the future, make it a goal!
