The insights I gleaned from the below links is:
Happiness comes from learning Torah, avodas Hashem, and emulating Hashem’s 13 attributes of mercy.
Start each day with keeping that message nearby so that when we feel a lack, we can ask ourselves to redirect our pursuit of happiness to learning Torah, avodas Hashem (davening, tehillim, personal prayer, mitzvahs) or emulating Him.
When we feel resistance, and we will, stop and pause and cry out to Hashem:
“Hashem it is my choice to focus on learning Torah, avodas Hashem and emulating You but my body is giving me resistance and telling me that (…be specific, feel it in your heart while describing it…) would feel better and be more gratifying and questioning my judgment and sending me all kinds of negative messages about my choice. I do not wish to be pulled into a vacuum that conceals the Truth that happiness comes from learning Torah, avodas Hashem and emulating Your 13 attributes of mercy despite this natural reaction. Instead, I recognize the design with awe and cry out to You to please help me. I wish the happiness You design for us.”
Then breath through it until you feel relief. It is dynamic. It may take 20 minutes or more of holding the feelings along with the feelings of love and awe for Hashem. Saying words without doing the work of holding the feelings together in the heart will not do anything lasting. The process is spiritually dynamic – the love and awe we generate in our hearts actually draws our neshama back from where it is trapped in the dark of our heartfelt reactions.
The main two middas are chesed and gevurah, and the harmonizing of opposites, tiferes. These are on the deeper level chochma, bina and daas. We want our daas to be the pure daas and not the daas of the nachash, which is natural to us.
