Decide what is important for you to achieve in your life. Mark some benchmarks as goal
A useful way of making a goal more powerful- be specific,measurable, mark what is attainable,and is relevant and after all make all these time bound.
Always have a routine and a time table. Let the two fail but you must have those even if you are past those. Re-draft those and keep them side by side those which could not be achieved.
Feed the assessment to yourself.
It is always requested and important not to set goals unrealistically high. It is important to set goals one can achieve. Set goals which can be foreseen and navigated by you.Write goals down.Keep goals small and always update.
Express your goal positively. 'Execute this technique well' is always a much better goal than ' Don't make this stupid mistake.
There may be several goals.Give each a pre-defined priority. Set measurable goals. These measurable goals can help you knowing exactly when you have achieved goal.
Achieve the gals and enjoy them .Draw satisfaction.Take the time to enjoy satisfaction of having achieved the goal.Absorb the implications of the goal achievement,and observe the progress you have made towards other goals,
If the goal was a significant one,reward yourself proportionately,appropriately.
Failures to meet/achieve goals do not matter as long as you learn from them. Feed lessons learnt back into your goal setting mechanism.
Remember too  that your goals will change as you mature. Adjust them regularly to reflect this growth in your personality.
If goals do not hold any attraction any longer ,then let them go.
Goal setting is your servant,not your master.
It should bring you real pleasure, satisfaction and a sense of achievement.

Never set them too low. We tend to do this to void the failure tag . We set a lower benchmark perhaps because we are really lazy.
