Break! 

Learning to program is hard. And building apps is hard. You’ll feel discouraged when you can’t get something to work just right. You’ll feel frustrated when you’ve been stuck for hours on the same problem. And you may want to quit when you don’t understand something. 

Learning to program is hard. And building apps is hard. You’ll feel discouraged when you can’t get something to work just right. You’ll feel frustrated when you’ve been stuck for hours on the same problem. And you may want to quit when you don’t understand something. But it gets easier. It turns into a puzzle. You’ll experience a rush of adrenaline when you hit the Run button and your app works. You’ll smile when you write code that runs perfectly on the first try. And you’ll celebrate when your first app goes live.
