Galatians 5 says, "You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace," and "a little yeast works through the whole batch of dough." That yeast is the law, a little law takes away a lot of grace. If you put even one law on yourself, God's old covenant law or your own invented law, then you are putting yourself in bondage.
You are to serve God by the Spirit not the old way of the law as Romans 7:6 says, "We have been released from the law, for we died to it and are no longer captive to its power. Now we can serve God, not in the old way of obeying the letter of the law, but in the new way of living in the Spirit." Serving God by the Spirit results in doing the good deeds described in the law and more. One difference is that there is no burden, no guilt, no shame, no condemnation. Serving by the Spirit is walking in the Spirit. It is a walk with God. It is not, as much of Christianity unwittingly practices, a walk without God trying to keep His laws and other moral laws (ones imposed by tradition, society, self, the church).
When you serve God by the Spirit you won't worry about "Am I doing enough? Am I spending enough time with God? Am I being a good witness?" and things like that. The primary questions are "Am I aware that He is with me?" and "Do I trust Him and His love for me?" When you serve by the Spirit you do what you see the Father doing just like Jesus did. We aren't to serve the law we are to serve God. It is falsely taught that serving the law equals serving God or that serving a church organization equals serving God.
"He is Lord of heaven and earth, he doesn't live in man-made buildings (temples, churches), and he is not served by human hands, as if he needed anything, because he himself gives all men life and breath and everything else." (Acts 17:24-25)
Hands don't serve God. It is His Spirit in you and the new living spirit He has given you through Christ that serves Him. When you replace "trust in Him" with "trying for Him" your life will have misery because you try to serve God with your flesh, your hands. Jesus said in John 6:63, "It is the Spirit who gives life; the flesh is no help at all."
Thankfully God doesn't judge you by works even if they are done by the flesh rather than the Spirit. He loves you because love is who He is. "Those who are in the flesh cannot please God. However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you" (Romans 8:8-9).
