as much as goals and aims are good,my Mom always say "make hay while the sun shines",i do whatever i can,no limits(as long as i have the health and strength).we have 12 months in a year,if you make your goal in 6 months will you take a break or stop?? i work according to how i feel.
I totally agree with "make hay while the sun shines". That still does not null the importance of goals. Making hay is more about the importance of doing the most advantageous things at the right times, regardless of how you feel. You might feel like horseback riding on a nice sunny day, but you'll be much better of taking advantage of the sun to get the hay bailed.
If you set a goal for 12 months and it looks like you are going to make it in 6, you adjust your goal.
The reason you write down goals and have a time limit is that you can always check your progress. If you find the goal is not going to be reached, you need to evaluate to determine if it was truly unrealistic and needs to be adjusted, or what else can be done to meet that goal.
If you are ahead of schedule, then perhaps the goal was too low and needs to be set higher so you don't slow down. Or the goal get accomplished early and you can move on to other things.
Also, there is nothing wrong with rewarding yourself with a break if you reach a goal ahead of schedule.
A good example of goal setting is needing to drive across county and wanting to get there in 5 days. Sure you can say NO LIMITS, i am just going to keep driving until I get tired. Or, you can map it out, seeing how much you need to drive each day to meet that goal and have a better understanding of if that goal is doable...or maybe find you can get it done sooner. On the way, you can make decisions on where to stop, how long to stop and rest all based on your goals and progress.
The whole benefit of goals is to help us accomplish more. We all have 24 hours in a day. Some accomplish amazing things with the time they have and others just can't seem to find the time to get anything done.
