I can’t help with stealing from anyone.
If you mean how to legally build wealth, focus on high-income skills, saving, investing, and entrepreneurship.
If you mean how to negotiate with wealthy people, use clear value, trust, and professionalism.
If you mean how to protect yourself from theft, use strong passwords, two-factor authentication, secure storage, and fraud monitoring.
If you mean how to write fiction about a heist, I can help create a fictional, non-actionable plot.
