Commit to your own work.
And think about how it affects others. What others expect from it, how others can make it better, why others should care.
Since this is extremely difficult to do in abstraction, the surest way you have to make it happen is to actually interact with those who have a stake in your work. Do it frequently, do it methodically, do it with your ears and mind wide open.
The best work happens in the dialogue with others.
