“When we least expect it, life sets us a challenge to test our courage and willingness to change; at such a moment, there is no point in pretending that nothing has happened or in saying that we are not yet ready. The challenge will not wait. Life does not look back. A week is more than enough time for us to decide whether or not to accept our destiny.”
― Paulo Coelho, The Devil and Miss Prym

“The brick walls are there for a reason. The brick walls are not there to keep us out. The brick walls are there to give us a chance to show how badly we want something. Because the brick walls are there to stop the people who don’t want it badly enough. They’re there to stop the other people.”
― Randy Pausch, The Last Lecture

“I have realized; it is during the times I am far outside my element that I experience myself the most. That I see and feel who I really am, the most! I think that's what a comet is like, you see, a comet is born in the outer realms of the universe! But it's only when it ventures too close to our sun or to other stars that it releases the blazing "tail" behind it and shoots brazen through the heavens! And meteors become sucked into our atmosphere before they burst like firecrackers and realize that they're shooting stars! That's why I enjoy taking myself out of my own element, my own comfort zone, and hurling myself out into the unknown. Because it's during those scary moments, those unsure steps taken, that I am able to see that I'm like a comet hitting a new atmosphere: suddenly I illuminate magnificently and fire dusts begin to fall off of me! I discover a smile I didn't know I had, I uncover a feeling that I didn't know existed in me... I see myself. I'm a shooting star. A meteor shower. But I'm not going to die out. I guess I'm more like a comet then. I'm just going to keep on coming back.”
― C. JoyBell C.

― Roy T. Bennett, The Light in the Heart

“The best moments in our lives, are not the passive, receptive, relaxing times—although such experiences can also be enjoyable, if we have worked hard to attain them. The best moments usually occur when a person’s body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile.

Optimal experience is thus something that we make happen. For a child, it could be placing with trembling fingers the last block on a tower she has built, higher than any she has built so far; for a swimmer, it could be trying to beat his own record; for a violinist, mastering an intricate musical passage. For each person there are thousands of opportunities, challenges to expand ourselves.”
― Mihaly Csikszentmihalyi, Flow: The Psychology of Optimal Experience

“Thunderstorms are as much our friends as the sunshine.”
― Criss Jami, Killosophy

― Erik Pevernagie

“Those who overcome great challenges will be changed, and often in unexpected ways. For our struggles enter our lives as unwelcome guests, but they bring valuable gifts. And once the pain subsides, the gifts remain. These gifts are life's true treasures, bought at great price, but cannot be acquired in any other way.”
― Steve Goodier
