If you aren’t taking on projects that make you uncomfortable, that make you sweat, that scare the living daylights out of you, then you probably aren’t doing a whole lot of growing.
Go on; do it! Take that step into something frightening and new! Being in a comfortable position means you aren’t taking risks and when you don’t wager your talent on something then your payout will never be significant enough to lift you out of your current situation.
Rise up, artists! It’s time to look to new horizons and run into the unknown with courage.
