My challenge was an open one by the way. To everyone who reads this message. It's not just my own personal challenge.
I agree that personal development is an ongoing process but I think I have gotten to a point where it is an unconscious competence thing. I no longer see things as opportunities to grow but just naturally do the things that best promote growth.
@lifeisamazing, you want better travel but a world without cars? I'm confused. I certainly can't see myself walking to America anytime soon (I live in the UK) and I can't even see myself walking to London anytime soon either.
@James81, from my own personal experience (and frustration) letting your own fire ignite others just doesn't work. I wish it were that simple. Cochonette alluded to this too. I'm so happy most of the time. I look around and I see good friends who are very unhappy but do they ask me for help or even quietly take notice? Hell no. Most of the time I get abuse (in a friendly way) for it.
Also, humanity and the planet are one element. It's unlikely that the planet will implode anytime soon, but irreparable damage can be done to the ecosystem quite easily. We continue to demonstrate this as a species. Without the planet and global ecosystem, humanity could not survive. Simple understanding of physics will show that if you dump enough greenhouse gasses into the atmosphere, your planet will end up like Venus. Even if humans were to disappear, the damage would have been done. That's not something I want for future generations of my species. It may seem that I'm going on about climate change a lot in this thread but I consider it the number one threat to humanity's existence and the sustainability of the planet.
I think it's worrying that a lot of people have an attitude that they are too small and insignificant to do anything. It is possible for one person to make a difference. That person just has to understand how the system they are working in operates and use their intelligence to leverage it in the most efficient way to get to their goals.
