Phil. 1:21 For to me, to live is Christ, and to die is gain.
What Paul says here is very rare, but not impossible. I assume, most christians wont or cant say this, for a variety of reasons. He is not elite, by no means, he just suffered more than most of us and because of that, greater revelation of God comes. We say, to live is Christ, yet often still have our own agendas. I can say, the longer I walk this out I find this statement to be more a lifestyle in my life. This isnt a requirement, but it is a relational deeper walk in Christ. Jesus did say, those who desire to be His disciples must deny himself, pickup his cross, & follow Him. When and how does one get here? Today, now, 1 step at a time walking in His love and grace. You and I can, as Paul, say this! I want to live the true life experience, its only found in Christ Jesus.
