You must change your attitude to life. Two people with same
boring daily routine but with different attitudes: The one person
has a positive and humorous attitude - enjoys even the boring daily
routine. The other person with a negative attitude - is depressed
from the boring daily routine and wants a change.
The other tips I can give you - do what you enjoy, if you enjoy
being with your friends, meet them as often as you can, go for
trips and so on.
I think first you must find out what you enjoy, what makes you
pleasure and then try to find the time for it. Do different
activities and find out.
