So, What is the deal, I'm a Jew? Now What?

Blessings and Curses, but for whom and how can I get this? Verse 10 says how!

Deuteronomy Chapter 30 דְּבָרִיםד

ח וְאַתָּה תָשׁוּב, וְשָׁמַעְתָּ בְּקוֹל יְהוָה; וְעָשִׂיתָ, אֶת-כָּל-מִצְו‍ֹתָיו, אֲשֶׁר אָנֹכִי מְצַוְּךָ, הַיּוֹם. 8 And thou shalt return and hearken to the voice of the LORD, and do all His commandments which I command thee this day.
ט וְהוֹתִירְךָ יְהוָה אֱלֹהֶיךָ בְּכֹל מַעֲשֵׂה יָדֶךָ, בִּפְרִי בִטְנְךָ וּבִפְרִי בְהֶמְתְּךָ וּבִפְרִי אַדְמָתְךָ--לְטֹבָה: כִּי יָשׁוּב יְהוָה, לָשׂוּשׂ עָלֶיךָ לְטוֹב, כַּאֲשֶׁר-שָׂשׂ, עַל-אֲבֹתֶיךָ. 9 And the LORD thy God will make thee over-abundant in all the work of thy hand, in the fruit of thy body, and in the fruit of thy cattle, and in the fruit of thy land, for good; for the LORD will again rejoice over thee for good, as He rejoiced over thy fathers;
י כִּי תִשְׁמַע, בְּקוֹל יְהוָה אֱלֹהֶיךָ, לִשְׁמֹר מִצְו‍ֹתָיו וְחֻקֹּתָיו, הַכְּתוּבָה בְּסֵפֶר הַתּוֹרָה הַזֶּה: כִּי תָשׁוּב אֶל-יְהוָה אֱלֹהֶיךָ, בְּכָל-לְבָבְךָ וּבְכָל-נַפְשֶׁךָ. {ס} 10 if thou shalt hearken to the voice of the LORD thy God, to keep His commandments and His statutes which are written in this book of the law; if thou turn unto the LORD thy God with all thy heart, and with all thy soul. {S}
