Joh To Tell you only to try Harder is Not helpfull.
Maybe I should put this in context.
The procedure is as follows: the belt is unlocked. First I clean the belt. I'll give this to my mum. Then while I'm showering she checks the belt. Before that, however, she once again warns me to be careful when showering.
If I don't pay enough attention when taking a shower, she warns me again. But then she also says that I should be more careful now and make an effort. That's what I meant by try harder.
