- A great day/night out with friends.
 - A book that I can read from cover to cover.
 - A whole day of complete freedom, that I can spend on the sofa watching old BBC comedies back-to-back.
 - A chance to lie-in past midday.
 - Freshly-squeezed orange juice.
 - Compliments (I'm very dependant on others' approval).
 - A good joke.
 - Listening to, singing along with, or playing good music.
 - Hearing a busker play a song I absolutely adore, and never expected to hear.
 - Reaching a milestone that I've been aiming for for some time (completing a game, for example, or passing an exam).
 - EoFF (sometimes, but it's just as capable of making me feel terrible if it wants to).
 - Those moments when I can sit in silence and feel content with everything around me.
 
There are many, many more, but those are the ones tha timmediately spring to mind.
