when people are young they have a vivid imagination but many youth only imagine and does not do anything ,which could be harmful,well speaking honestly.....i am one of them .always imaginting a lot of stuff but haven't done anything yet .we are often afraid of out side world as it is changing in a blink of eye and we couldn't do anything rather than sitting and watching the change ,and maybe the other reason could be because we are afraid that other person could laugh at us or does not understand us .but in this we forget that they are no one to comment on us .still we try to impresse those unimportant people in our life.
