How can i get back into gaming ? lost of interest?

i still recalled the time i played for the first time wow, i learned about it at school was with some friends who were talking about this fantasy world that got me hooked instantaneously, after school went with 3 usbs and went to my friends house just so i can get the installer and play on free server, i stayed almost 24 hours straight trying to lvled up; now days i can barely get any joy out of a game i play, i can barely stand half hour of one till i get disinterested, and idk why, i still have that desire to play but lack of interest i guess ?
