How do you or I best impact the world for God's glory?
When we shine God forth in a way most suitable to our abilities, gifts, talents, resources, and experience. No matter who you are or what you do - be that a truck driver, a sales person, a surgeon, a cashier, or an author etc. - do all to the glory of God.
The good news is we are not rewarded based on our gifts but our *faithfulness. Bringing God Honor has nothing to do with our "station" in life but our heart i.e. why we act. The more we use whatever gifts God has given us, for His glory, the greater our reward.
In so doing, we must also recognize we will encounter resistance - thorns, and thistles - in our efforts, no matter what we do. Even if you are doing what you love to do there are still mistakes, failures, accidents, loss, damage etc. A difficult path does not mean it's the wrong path. We are not supposed to quit because we encounter difficulties, it simply means we're broken and live in a broken world. Christ said, "in this world, you will have trouble (tribulation)..." It is inevitable. There is no "if" or "when" we will encounter challenges, only how we will.
Persisting in using what God has given you in the face of great opposition actually brings Him greater honor and glory. It shows you value him and desire to honor Him more than the comfort you set aside to pursuit him - i.e. your desire to show him forth out of love for him is greater than any distaste of pain you may encounter in doing so.
So whatever you set your hand to do, do it with persistence and for his honor. And when you're done he will tell you "well done good and faithful servant..." enter into your rest and reward. Rest implies there was struggle in accomplishing your task. Not just any task but a good and right one.
There is no complete avoidance of pain in this life. That comes later. For now, we have the opportunity to "fill up" the sufferings of Christ and let them prepare us to take part in heavenly glory, which is a face to face union with God himself.
