1) The next 5 of the 20 Ikarim of Teshuva are:

11. Search your soul and make an accounting of your actions, so you will recall all your forgotten iniquities and be able to say Vidui for them, humble yourself because of them and resolve never to repeat them.

12. Investigate the magnitude of each of your sins. Determine which punishment you deserve for each of them [Malkos- 40 lashings, Kareis- heavenly death penalty or Misas Bais Din- capital punishment meted out by a rabbinic court of law. Though Malkos and Misas bais Din aren't in effect today, as we are in Galus, variations of them are meted out through the heavenly court for those who deserve them] and do the appropriate Teshuva for each of them.

13. Consider even the seemingly insignificant sins as grave sins in your own eyes; don't dwell on the smallness of the sin, rather dwell on the greatness of the King [Hashem] who commanded you to do His will.

14. Explicitly enumerate each and every one of your sins (Vidui) as well as the sins of your forefathers. (as repeating sins they did is in itself a sin; one is supposed to  learn from mistakes of his forefathers and not repeat them)

15. Pray to Hashem and beg Him to have mercy on you and forgive you and erase your sins and purify you from their harmful effects.

2)The final 5 of the 20 Ikarim are:

16. Repair your wrongs. Return the stolen items if you stole, or beseech your friend for forgiveness if you spoke Lashon Hara (evil gossip) about them or embarrassed them or other similar sins against your fellow man, as there can be no atonement from Hashem until you secure forgiveness from your friend.

17. Seek and do acts of kindness (e.g. Tzedaka and Gemilas Chasodim) and give support to people who advance truth such as Talmidei Chachamim and Torah scholars, and stay away and shun falsehood.

18. The [details of your] sin should remain in your mind always until the day you die (in order to remember not to repeat them, but not Chas V'shalom to get depressed from them)

19. Let go of the Sin. If the opportunity arises again to do the identical sin, conquer your Yetzer Hara and run away from the [place of] sin, as you would run away from a sword that was pursuing you, because of your fear of Hashem. And even if the same opportunity of sin does not present itself again, have in mind during Krias Shma, when saying the words "B'Chol NafShecha" that you are willing and ready to give up your life in order not to transgress the 3 cardinal sins (murder, idolatry and sexual immorality), and it will be considered as if the opportunity arose, and you withstood the test and didn't transgress.

20. Facilitate the repentance of others. Causing others to sin is one of the worst things to do, and on the other hand, causing others to do good deeds and/or repent is one of the most worthy things a Jew can do, and is also very vital to his/her own Teshuva.
