The mind is not neutral. It can help you think clearly or trap you in loops that lead nowhere. When it is trained, it serves to analyse, decide, and move forward. When it is left unchecked, it tends to repeat fears, doubts, and scenarios that do not exist. Not everything it says should be believed.
Learning to use it means knowing when to listen and when to step aside. Some thoughts provide information, others only create noise. The first deserve attention. The second should be allowed to pass. That difference shapes how you live day to day.
