an ability to recover from or adjust easily to misfortune or change
a feeling of indignant displeasure or persistent ill will at something regarded as a wrong, insult, or injury
(Merriam-Webster's Online Dictionary)
Do not resent the world for disturbing your writing. Make your writing process resilient to the interruptions of the day.
If you have planned to write all day you have made too big a target of your process. A vaguely planned writing session is easily interrupted.
Set off a few hours every day, or every other day, to write. Let the world do what it may outside your door. Write, and then go back to the world.
Do not resent the world because it needs you. Do not think it needs you so badly that there is no time to write.
