Yes. In Jain practice you can renounce one bad habit and simultaneously strive for multiple good outcomes.

How it works:

• Vairagya (detachment) and tapas (austerity) are about reducing karma by decreasing harm. You can choose to abandon one vice (e.g., violence, lying, stealing, etc.) and set several positive aims at once (e.g., greater compassion, more self-control, and clearer understanding).
• There is no rule that you must limit yourself to only one goal. In fact, pursuing multiple wholesome aims together often strengthens your restraint and progress.
• Keep your goals aligned with Jain principles: non-violence (ahimsa), truth (satya), non-stealing (asteya), celibacy or proper conduct (brahmacharya), and non-possessiveness (aparigraha). If your two desired outcomes support these vows, they are proper to pursue.
• If there are differences between Digambara and Śvetāmbara interpretations on specific practices, you can follow the guidance given by your own tradition while keeping the underlying aims of purity and self-improvement.

A simple example: you choose to quit lying. At the same time you aim to cultivate truthful speech and increasing compassion in your interactions. Both outcomes support right conduct and purify the mind.

If you have a particular habit and two specific goals in mind, tell me the details and I’ll explain how they fit with Jain vows and how to approach them.
