TEDxPetalingStreet 2018 的主题视觉，以文字作为重点出发，传达“燃”的核心概念：“对于理想的热情，需要靠持续努力与勇敢坚持方能达成。 点燃内心那把斗志与热忱之“火”(PASSION)，重点不在于一刹那的耀眼光辉，而是期许后续持之以恒的“然”后 (ON and ON)。漫漫耕耘过程难免会有怀疑、否定、犹豫、挫折等等障碍，通过这些否定与矛盾 (NO) 来不断自我审视和反思，从中推动学习与成长的轮轴，如同每人心中的那头猛虎，驱使你勇往直前，继续迈步 (ON)。恒持初衷里的一份炽热决心与万丈热情，顺逆交迭之间展现坚毅不拔的精神，超越极限，才是人生永续不灭的能量。这正正呼应主题“在岁月中激情燃烧自己，天生敢为，真我不藏，你终将在时代的苍穹里绽放属于自己的光芒。” — 所期盼的那股巨大力量效果。

The pursuit of ambition can only be achieved through consistent effort and continuous courage. "Passion is just the beginning!" This is the main concept behind the art direction of TEDxPetalingStreet 2018. While it is “PASSION” that ignites the enthusiasm to chase a dream, its success is not determined by the moment of brilliance that happened at that time. Rather, it is a long, gradual process that involves doubt and belief, hesitation and confidence, frustration and triumph - hence the repetition of the final two letters into an interlinked chain of  “ON” and “NO”, which represents the opposing forces that shaped this learning and reflective experience. This is exactly what the theme echoes : “Burning our fire bright in years, born to be bold , daring and unleash one’s true self, your light will shine in the time of era. ” that is the effect of great power that is accumulated through perseverance.
