Easy. I’ll tell you how…
First… read the Artscroll book 5 Great Lives.
Then Sefer Chofetz Chaim. Either the Artscroll blue book or the recently Israel Book Shop one which is very good.
Then Orchos Tzaddikim to learn the good/bad side of 27 different emotions.
Then Derech Hashem from the Ramchal to understand the world.
Then Mesilas Yesharim by the Ramchal too.
Then beware, your yester hara within you will become stronger to compensate for your increased level. You are a capital asset of several decades investment. The goat face will not take losing you well. Further be advised, he gets vengeful if you make too much teshuva — any teshuva — and is known for striking at the people close to you out of spite.
At that point it is vital to read the book Remove Anger from Your Heart. That yellow book. Vital.
This is for a man.
For a lady… hmm, long skirt to the ground will cause the malachim to “smooth your path.” I would also recommend reading the short book Geder Olam (modesty in dressing, not mix dancing at weddings, married hair covered). The Feldheim edition is very good. Honesty, be sincere and speak nice never gossiping, and Heaven will help.
