Galatians 6:4

4 But let every person carefully scrutinize and examine and test his own conduct and his own work. He can then have the personal satisfaction and joy of doing something commendable [in itself alone] without [resorting to] boastful comparison with his neighbor.

We can only do this when the Holy Spirit has set us free from all condemnation and guilt.

Therefore, [there is] now no condemnation (no adjudging guilty of wrong) for those who are in Christ Jesus, who live [and] walk not after the dictates of the flesh, but after the dictates of the Spirit. Romans 8:1

And He will establish you to the end [keep you steadfast, give you strength, and guarantee your vindication; He will be your warrant against all accusation or indictment so that you will be] guiltless and irreproachable in the day of our Lord Jesus Christ (the Messiah). 1 Corinthians 1:8

As long as we feel that we have to first measure up, or keep a set of laws on our own, we will feel condemnation, because we can never measure up on our own. What will happen is when we feel condemned for failing, we will look at others to see if they are measuring up, because misery loves company! Then when we feel that we have succeeded at something, we will boast about it as we judge and condemn others who have failed. So to set us free from all of this, Jesus has made us dead to all religious laws.

Likewise, my brethren, you have undergone death as to the Law through the [crucified] body of Christ, so that now you may belong to Another, to Him Who was raised from the dead in order that we may bear fruit for God. Romans 7:4

The only way that we will ever be used to produce fruit is when the Holy Spirit empowers us to know that it is always the power of our Father working through us that produces it. We test our conduct based on Jesus. We never look at ourselves, we always look to Jesus.

Looking away [from all that will distract] to Jesus, Who is the Leader and the Source of our faith [giving the first incentive for our belief] and is also its Finisher [bringing it to maturity and perfection]. He, for the joy [of obtaining the prize] that was set before Him, endured the cross, despising and ignoring the shame, and is now seated at the right hand of the throne of God. Hebrews 12:2

We do all things through Christ Who strengthens us, Philippians 4:13. We are more then conquerors through Christ, Romans 8:37. Without Jesus we can do nothing, John 15:5. We have the complete satisfaction that Jesus will succeed through us.
