Well, I think you're mixing two phrases, Ticcota:
enjoy = to derive pleasure from something, enjoy the film; this phrase requires an object
enjoy oneself = have fun;
I think you want the second phrase, not the first one.
EDIT: On second thought, your second sentence could probably work as it is because trying can be seen as gerund and an object, but I don't like the sound of those two -ing forms one after the other. Maybe it's just me.
