How do you cope with the feeling when you`ve been grinding hard for 10days straight you are running good... and then in two sessions you burn everything you've made ?

I`ve gone through this a couple of times... sometimes there are mostly only bad beats... other times it is because of bad play but usually both.

How do you go through this kind of experience?... grinding for a long period of time then burning everything in like 2-3k hands? (I know 10days it is not such a long period of time but still).

Thanks!
