"When it is important for you to say something and you find a vehicle to say it, then go for it. It is so rare when that happens so I think every minute spent fighting for it is always worth it. Even if nothing ends up happening, it's still worth the fight"

In this quote, Salma Hayek stresses the significance of taking opportunities to express oneself, particularly when what you need to say holds personal significance. The "automobile" she describes is a metaphor for the medium or platform that enables you to communicate your message effectively-- whether that be through art, public speaking, composing, social networks, or another type of communication. When such an opportunity emerges, Hayek motivates maximizing it ("then go for it"), underscoring the rarity and preciousness of these moments.

The expression "It is so rare when that takes place" shows her belief that finding both the right message and the suitable methods to deliver it in tandem is not a frequent incident. Life typically throws many barriers that can silence voices or water down messages, making the effective articulation of one's thoughts a coveted occasion. As such, the act of voicing crucial concepts becomes a pursuit worth dedicating energy towards.

Hayek further advises that every moment spent promoting for one's views is inherently important ("every minute invested fighting for it is always worth it"). This recommends that the intrinsic act of striving for self-expression holds its own benefit, despite the outcome. The journey of fighting for the chance to be heard is depicted as a gratifying undertaking, enriching one's sense of purpose and firm.

Lastly, the concluding part of the quote ("Even if nothing ends up happening, it's still worth the fight") serves as a reminder of the intrinsic worth of the battle itself. Even when external results are not visible, the personal development, complete satisfaction, and durability got from standing up for what you believe in validate the effort. Hence, the worth lies not just in potential victory but also in the courage and commitment showed in the effort. Hayek's message champs the empowerment discovered in articulating one's truth, no matter external recognition or success.
