Lakshmi, the goddess of fortune, is called chanchal. Use it in worship of Lord Krishna.
The Lord can be served simply by adoring Him and accepting Him.
Srimad Bhagavatam 2.9.36,
A pure devotee has no demand from the Lord. His only concern is to serve the Lord sincerely and seriously and he is not at all concerned about what will happen in the future. — Srimad Bhagavatam, 04.09.29.
Material sense gratification, sinful activity kills the propensity to serve Krishna.
Hammer every thought in your mind thinking of how to serve Krishna.
