deny self
Then Jesus said to His disciples, “If anyone wants to come with Me, he must deny himself, take up his cross, and follow Me.”—Matthew 16:24
Sin causes us to be self-centered, shifting our hearts from God to self. The essence of salvation is an about-face from self-centeredness to God-centeredness. The Christian must spend a lifetime denying self. Our great temptation will be to affirm ourselves while we follow Jesus. James and John did this when they chose to follow Jesus but asked for the two most prominent positions in Jesus' kingdom.
Then James and John, the sons of Zebedee, approached Him and said, “Teacher, we want You to do something for us if we ask You.”  “What do you want Me to do for you?” He asked them.  They answered Him, “Allow us to sit at Your right and at Your left in Your glory.”  Mark 10:35-37 (HCSB)
James and John wanted a discipleship that would not impede their personal desires and aspirations. Like them, we say, “Lord, I want to be pleasing to you, but I want to stay where I am.”

Self-centered people try to keep their lives unruffled and undisturbed, safe and secure. Our temptation is to give our time and effort to the goals of this world. Then, when we are successful in the world's eyes, we seek to bring God into our world by honoring Him with our success. We may say, “Now that I have succeeded in business [or sports, or politics, or with my family, or even Christian ministry], I want to give God the glory for it!” God is not interested in receiving secondhand glory from our activity. God receives glory from His activity through our lives.

The world will entice you to adopt its goals and to invest in temporal things. Resist the temptation to pursue your own goals, asking God to bless them. Rather, deny yourself and join the activity of God as He reveals it to you.
