On Patience
Patience is active, not passive. What does this mean? It mains patience doesn’t just “happen”. You must strive for it. You have to actively remind yourself and make yourself patient.
Also, remember that Allah (سبحانه وتعالى) tests you with what you are not patient with. If He (سبحانه وتعالى) tested you with things you already succeed at, how could you ever learn and grow?
For a classic example of patience, consult Surah Yusuf.
