That is absolutey the worst advice I have ever heard. Firstly everyone and every situation is totally different. Secondly you could have a shitty week for thousand of reasons, it doesn't mean things won't change drastically. Thirdly, advising people that giving up after one week in any situation is a good life tip is completey the reverse. If you give up things before you have barely tried you will have a crap life where you just don't bother. This really is some crap advice.
