Why in the book pauls case does paul go to work early?

Paul spent much of his time traveling in his preaching work, as he spoke about God's Kingdom and proved that Jesus was the Christ. When he arrived in Corinth, he stayed with Aquila and Priscilla, since he, like they, were tentmakers by trade(Ac 18:1-3) and he did not want to become an expensive burden to the congregation. Paul worked to pay his way(1Thessolonians 2:9; 2Thessolonians 3:8)and continued to 'give free'.(Matthew 10:8)
