I was always told to get outside your comfort zone.
Meaning if you are mostly shooting street shots or landscapes try shooting portraits or shooting people in general.
And so forth, usually getting out of your comfort zone forces you to grow as an artist or photographer.
Sometimes its as simple as taking only your 50mm with you for a week and forcing you to think about each shot.
These are pointers that have been given to me.
