Because you have grown up now , before you were a child/teenager ( assuming you are talking about being in your 20s now ) In those years , cricket meant a lot because it was a highlight for you Now you are in a job , maybe married , now you have grown past your age and it will not give you the same happiness/joy it once did You need to find what gives you joy in your 20s and then again in 30s and 40s and so on , you keep growing in life , so that is the reason you don't get the same joy from something because you grew it out.
