To quote from The Imitation of Christ, a part of a passage I read today:
"The pure, simple and steadfast spirit is not distracted by many labors, for he does them all in the honour of God. And since he enjoys interior peace, he seeks no selfish end in anything. What, indeed, gives more trouble and affliction, than uncontrolled desires of the heart?"
Lately, I find myself being distracted by the many things I have to do: work, study, visits to friends, calls to home etc. It's easy to get overwhelmed but this passage offers me solace.
