Ben Sira 11:10

10 My child, don't get involved in too many things. If you try to do too much, you will suffer for it. You won't be able to finish your work, and you won't be able to get away from it either.

Ben Sira 11:10 In-Context

8 Don't interrupt while someone is speaking; hear what he has to say before you answer.
9 Don't get into an argument over something that is none of your business. Don't take part in decisions that are being made by sinners.
10 My child, don't get involved in too many things. If you try to do too much, you will suffer for it. You won't be able to finish your work, and you won't be able to get away from it either.
11 For instance, here is someone who never stops working like a slave, but gets further behind all the time.
12 On the other hand, someone else may be very poor and not up to his task. He may be slow, and he may need help, but the Lord is pleased with him and pulls him out of his bad situation.
