Mark 6:12 So they went out and preached that people should repent.
What do you do for a living? How much of your time is actually spent talking to other people about God?
I know it may seem like we talk for a long time to others straight after church or before church, but in reality the time we spend is very short in comparison with other subjects.
The disciples went out to go and talk to people about God. Not as a side line but as their main task.
We do have to make a living and so we need to be able to work to earn money; but work should not exclude us from spreading the good news!
