No of course you must be honest, but I am just giving suggestions for things you might be good at. For example, I have seen some applications where people have put that they are very good at writing....well, great, but I want you to put frozen food out quickly when under pressure, so it isn't a relevant skill. Skills such as listening, consistency, hard working, team work, fast learner, flexible, customer focused etc are all relevant. And EVERYONE is good at one of those things.
So yes, always be honest on an application form. But some people are good at such things, but just need some guidance on what to include.
