"Concerning each individual, and regarding the particular part of a misdeed, distinctions are made in judgement." (Ohr Yisrael, Letter Six)
What difference does it make that are different parts of the misdeed -- isn't the judgment only dependent on whether or not we upheld the Torah?
HaShem considers each Mitzvah to comprise different parts -- some relatively easy for the person to observe and some difficult for him to observe.
For instance, Steve was raised in a non-observant home. For the last several months he has been learning about the laws of Shabbos. However, he is not yet ready to be fully observant. He would like to keep Shabbos, but he owns a flower shop and Saturday is his busiest day. The best course of action would be for him not to work on Shabbos.
Steve discusses his situation with Rabbi Steinberg. The Rabbi says, "I hope that in the near future you will observe Shabbos. In the meantime, there are certain things that you can do that will lessen your violation of Shabbos without hurting your business.
Normally Steve carries a key to open the shop. Rabbi Steinberg advises Steve to arrange for his non-Jewish worker to open the door on Shabbos.
Steve is happy to comply with the "easy" aspects of Shabbos observance. Rabbi Steinberg shows Steve clever ways in which he can observe Shabbos according to his level of commitment. The positive reinforcement from Rabbi Steinberg's suggestions, as well as the happiness that he is observing Shabbos to some degree, encourages Steve. Over the course of the next few months Steve stops working on Shabbos altogether.
Tip -- Think of a Mitzvah that you are lax in and see how you can come to fulfil it by tackling the easy parts first.
