Do hard things
Most people choose easy over hard. But those who achieve "big things" are those who do hard things. Ambitious people try to do hard things and some do hard things better than others.
As a follower of Jesus, I do not see "success" the same way as the world sees it. But that does not mean I ought to choose easy. No, I ought to do hard things. To build myself up so I am ready for whatever God calls me to do for his glory.
Do hard things for Jesus.
"... [with joy] let us exult in our sufferings and rejoice in our hardships, knowing that hardship (distress, pressure, trouble) produces patient endurance; and endurance, proven character (spiritual maturity); and proven character, hope and confident assurance [of eternal salvation]."
