Change is a process. It does not simply happen to you. The rewards of your efforts are not immediate.
As Peninah Nthenya Musyimi says: if you want something you've never had, you must be willing to do something you've never done.
We tend to focus on all of the reasons why something cannot be done, why something cannot work. In doing so, we rob ourselves of the opportunity of actually testing that . We rob ourselves of making the effort to change. We rob ourselves of making the effort to improve our lives and the world around us. So much could change if each person was to let go of the opinions that start with the belief that "it cannot or should not". How many times and in response to how many scenarios have you heard someone say "that's just how it is, there is nothing we can do to change it"? Many, many times and in many, many scenarios. This is another way for someone to say "it cannot change" - but without bothering to test that belief. The opinion becomes more real than the potential reality you can create - that OPINION is what stops people from taking ACTION. That OPINION is what allowed this world to be the way it is. That OPINION is what allowed the pain and suffering in this world to exist.
Go with the choice that scares you the most - it is the choice that requires the most of you - Another cool suggestion from Peninah. Do that which you resist - you will often find the greatest gifts in those things.
People achieve more and do more when they know that not doing so will mean that nothing will change - people who come from poverty or abuse do MORE to change their lives - because they know that if they do not then they will stay in their own personal hell. Often this only happens when opportunity is GIVEN to them - there are very few people who can independently create themselves and their opportunities from nothing. Unfortunately, these few success stories are used as a fantasy for other people, they are not effectively used to support people, only to show them how to dream - so many people do not take the next step from dreaming to DOING - this is where the fantasy falls short. These stories should be shaped and shared in such a way that they also show HOW to create change, not only that it is possible.
The spiral effect of 1 + 1 + 1 ends up making big ripples in communities. Supporting one person to change themselves will in turn give that person the opportunity to support and share with others as well. It will give them the opportunity to teach their children things they may not have taught otherwise, things that will support their children in creating their own opportunities and in turn resonating the effects of that teaching into the community. One person at a time quickly accelerates to 2, 3, 4, 5.... 100 people - imagine if every single person who already has so much opportunity to make changes - not only for themselves, but support others as well - imagine if each of them supported only one other person who is not so fortunate. In time, that one person can then support another person of their own and so on and so forth. This may sound "small", it may sound insignificant and impossible to effect real change in the world - this is simply because we have become so ineffective at seeing the potential objectively, at investigating fully how far it could go. We have become slaves to our perceptual fallacies and biases - effectively re-enforcing our already ignorant behaviour. We have limited ourselves in what potential we see in ourselves and in others - we have become stuck in opinions that keep all of us limited.
Changing ourselves and the world is as simple as stopping our opinions of the way things are. In reality, most of the things we believe come from fallacies of thought and perceptual biases (we do not see things for what they are). It is our own ignorance and lack of self awareness that has gotten us to this point - this is where we must take responsibility and change ourselves for the good of the entire world.
