Rabbi Hanania ben Akashia says “The Holy  One – Blessed be He – wanted to give merit to Yisrael – therefor he increased the Torah & Mitzvot – as it says “Hashem – because of his Righteousness – increased the Torah and made it mighty.” (Pirkei Avot 6:11)

רבי חנניא בן עקשיא אומר רצה הקב”ה לזכות את ישראל לפיכך הרבה להם תורה וכו’

Some explain this as – G-d wanted a person to observe more mitzvot so he gave them a greater quantity of Mitzvot. The Rambam – Maimonides explains – that G-d gave a person a greater choice so that they could choose one mitzvah to do with the best quality.

If one does one Mitzvah to perfection – he or she will be able to receive a portion in Olam HaBa / the World to come.

Rav Shaked Bohdana explained in a Shiur / lesson that the key word is “Meyamay” / in all my days. In the Talmud – we have Kimchit that had 7 Chief Kohens . Cohen Gadol serve in the Beit HaMikdash / the Holy Temple. What was her merit? She responded “In all her days she never let the wallls of her house see her hair uncovered.” (Talmud Yoma / 47a) Meaning she was exemplary in the trait of being modest / Tzanuah. Rabbi Hanan

Rabbi Adda bar Ahava lived long. The sages asked what was your merit that you have long life? He responded In all my days I was never never angry in my household and I never walked in front of a sage that was greater than me. (Talmud Yoma / 47a)

Rav Bohdana mentioned that doing a good need regularly applies not only to a mitzvah from the Torah or From the Sages – but to a good character trait – like we see from Rav Adda bar Ahava.

Consistency is key. When we find a mitzvah that we feel is particularly important – doing it to perfection will give us great merit in this world & reward in the next.

How do we find a mitzvah that we find important? See what good deed or mitzvah or good action that we find important and learn about the details in the Torah and be consistent.

Two small points: One – because we do one mitzvah to perfection – it does not mean that we neglect the other Mitzvot.

Secondly – we should assure that something is a mitzvah from the Torah according to an competent Orthodox Rabbi before we take upon ourselves something that we feel is a Mitzvah. Someone might think giving out cigarettes or encouraging people in a certain way of life is a Mitzvah – it might be just the opposite. Get things clear before you start.
