I am always trying to find a “formula of life” so that I can easily find, and hold onto, happiness.
In order to be truly happy, people must have a real relationship with God (Psalms 16:11). And the only way to have a real relationship with God is by being a Christian (John 14:6).
If people haven't become Christians yet, all they need to do in order to become Christians is believe that Jesus of Nazareth is the Christ, and the human/divine Son of God (John 20:31, John 3:36; 1 John 2:23), and that He suffered and died on the Cross for our sins, and rose physically from the dead on the third day (1 Corinthians 15:1-4, Luke 24:39,46-47, Matthew 20:19, Matthew 26:28).
After people become Christians, in order to help develop and keep up their relationship with God, they should pray to Him every day, such as with The Lord's Prayer (Matthew 6:9-13), praising and worshipping Him (Revelation 4:11), confessing their sins to Him (1 John 1:9), asking Him for what they need today (Luke 11:3), and thanking Him for everything which He has given them (Philippians 4:6). And throughout the day, they should immediately bring to Him in prayer anything which they become worried about at any time (Philippians 4:6-7).
They should also fellowship with other Christians every day (Hebrews 3:13, Hebrews 10:25), at least in some fashion (Matthew 18:20), such as on this forum, being exhorted by them, and exhorting them in turn (Hebrews 3:13).
They also need to examine themselves in order to make sure that they are truly in the Christian faith (2 Corinthians 13:5, Proverbs 28:26, Proverbs 14:12). The way to do this is to read every word of the Bible (Hebrews 4:12, Matthew 4:4), and see if they accept everything it teaches as having came from God (John 8:47; 2 Timothy 3:16). For just as true Christian faith will initially come from reading (or hearing) what the Bible teaches (Romans 10:17; 2 Timothy 3:15), so people can know that they are remaining in the true Christian faith, if they continue to believe that everything the Bible teaches came from God (John 8:31b; 2 Timothy 4:2-4; 1 Timothy 4:1, Mark 8:35-38).
In order to have any real relationship with Jesus, and God the Father, and the Holy Spirit (Matthew 28:19), most importantly people must believe the right things about Jesus (John 14:6-7): that He is God the Word made flesh (John 1:1,14), that He is the Christ (1 John 5:1; 1 John 2:22), and that He is the only begotten (only born) Son of God (John 3:16,36; 1 John 2:23), meaning that He is the only person ever born without any human father (Luke 1:34-35). And people must believe that Jesus lived a perfectly sinless life (Hebrews 4:15; 2 Corinthians 5:21), and so He could suffer and die on the Cross for our sins, and rise from the dead on the third day (1 Corinthians 15:1-4). He rose, and will remain forever, in an immortal flesh and bones human body (Luke 24:39; 2 John 1:7), as Christians' eternally-human high priest/mediator (1 Timothy 2:5, Hebrews 2:16-17, Hebrews 7:24-26).
Once people come into faith in Jesus Christ, they must obey Him, and God the Father, and the Holy Spirit, by repenting from their sins, and getting water-immersion (burial) baptized into Jesus (Acts 2:38, Romans 6:3-5, Galatians 3:27). And they must partake of the divine flesh and blood of the bread and wine of Communion (John 6:53, Matthew 26:26-28; 1 Corinthians 10:16; 1 Corinthians 11:27-30). And they should get hands laid on them to receive Holy Spirit baptism (Acts 8:17), and one or more of the Holy Spirit's wonderful Spiritual gifts (Acts 19:6; 1 Corinthians 12:8-10). Then, washed from their sins by water baptism (Acts 22:16), and empowered by the Holy Spirit within them (Acts 1:8, Ephesians 3:16), they must each and every day, for the rest of their lives, deny themselves, take up their crosses, and follow Jesus (Luke 9:23; 2 Corinthians 5:15), by continuing in the faith to the end (Hebrews 3:6,12,14, Hebrews 6:4-8, John 15:6; 2 Timothy 2:12), by repenting from every sin which they commit (Hebrews 10:26-29; 1 Corinthians 9:27, Luke 12:45-46), and by doing to the end the particular spiritual works which He has given them as individuals to do (Mark 13:34, Romans 12:6-8, Titus 3:8).
But if they as Christians wrongly employ their free will to refuse to do these things, then they can't expect to have any continued real relationship with Jesus Christ, and God the Father, and the Holy Spirit. For a continued real relationship with them requires that people not only continue to believe in them, but also continue to obey them (John 15:10, John 14:21,23). Faith without works is dead (James 2:20), and can't ultimately save people from hell (James 2:14-26, Romans 2:6-8, Matthew 7:21, Hebrews 5:9).
