yom kippur - Techniques for preparing for teshuva?

I'm attempting to prepare for Yom Kippur, and among the preparations is the issue of determining what, exactly, I should be focusing on during viduy this year. I'm curious whether there are any particular techniques espoused by either chazal, modern Roshei Yeshiva, or other notable Torah personalities regarding this topic. Currently, I'm simply attempting to compile a list of aveiros or la'avim that I find myself struggling with; if there are any better ways of going about this, I'm curious.

Note: I'm not sure whether this question is appropriate for this more halachic-oriented forum, so feel free to close it if necessary.

Answer

This may not exactly answer your question, but Sharei Teshuva (as well as Rambam) brings 24 categories that impede teshuva:

1. One who frequently spreads Rechilus (slanderer)


2. One who regularly speaks Lashon Hara (Gossiper)


3. One who gets angry quickly


4. One whose bad (impure) thoughts control him


5. Being connected to a rasha (evildoer)



6. Taking from food that isn't sufficient for its owner


7. Gazing at Arayos with sinful intent


8. Partnering with a thief


9. One who says "I will sin and repent afterwards" or " I will sin and Yom Kippur will atone for the sin"


10. One who derives honor [and pleasure] from his fellow man's humiliation.


11. One who separates him/herself from the Tzibbur (congregation).


12. One who ridicules his forefathers and/or teachers


13. One who curses the public


14. One who prevents a group of people from doing a Mitzvah


15. One who causes another Jew to leave the good path and take a bad path [of living not according to the Torah]



16. One who uses the pillow of a poor person [i.e. causes a poor person to lose the use of any of his meager possessions]


17. One who accepts bribes in order to skew and distort justice from prevailing.


18. One who finds a lost object and doesn't [try and] return it to its proper owner.


19. One who sees their child going off the [Torah] path, and doesn't admonish them.


20. One who eats [i.e. usurps] the food [i.e. livelihood] of poor people, orphans or widows.


21. One who argues [and does an action] against the will of the sages.


22. One who accuses good people of doing wrong [without proper proof or reason]


23. One who hates [and cannot accept constructive] criticism.
