How should youth set thier goals to achieve success in Life?

in my view the most important thing is that they should be crystal clear of their goal or aim in life.. the main problem they face is that they do not have a single goal at on time,you should always set up some sub targets in life,you have to achieve these targets one by one to reach the ultimate goal. one must possess strong determination and great motivation to achieve what he wants to achieve. i wish all the mylotters what they wish for themselves.
