Why is it so important to realize your goal ? Firstly you have to realise what your goal is because setting goal isn't just about getting reward but in the person you become as a result of reaching your goal.
I personally observed many people who are so devoted towards their goal that they just want their destinatination any how and that's appreciable too but people forget to enjoy the path in the process or we can say they just want to enjoy when they get what they want . According to me this stratergy of achieveing success isn't appropiate as until you are not enjoying what you are doing how can you be happy through out the process and happiness is the key to success.
So start enjoying what you are doing because even if you won't achieve what you want atleast you will be happy that you enjoy the whole path and through that you became a much better person than you were used to be like you built yourself more discipline , consistence, self realince and you started enjoying everything you do you will love to discover new things, ideas and all . So rather thn savoring only the reward that have flowed from the achievement of that goal, celebrate the fact that the process of reaching your destination has improved the person you are.
GOAL is something the defines the meaning of life SET IT WORK FOR IT ACHIEVE IT and most importantly ENJOY IT!!
