Overcoming the fear of Change rationally

The only constant is change. Or so we remind ourselves so often. Why? Because like it or not, at one time or the other, we all have feared change. Change is the unknown and we have a tendency to fear what we do not know. In Step5, we deal with change itself. This is simply because the solution we choose to solve our problem will undoubtedly bring out change.
I've talked about before that in order to start changing, we must first accept change. Accepting change allows us to face change without the mental weights of thinking how to resist change and finding ways to keep the status quo. I've also mentioned that sometimes we should overcome fear of change by simply being impulsive.
But let's say we learned something new but are hesitant to apply what we learned. It's there but not put to use. Like a tool that we bought but still in the packaging. The reason for this hesitation is because it is a form of fear of change. Specifically, we are unsure whether that new thing we learned is better than we already know. We wonder whether it will produce better results that what we normally do.
One way to overcome this fear is to go over the previous unsuccessful attempt. By repeating steps we've taken before, we can be sure not to miss anything. Another way is to overcome it rationally. First, we rationalize how we got to this point. Either what we were doing before wasn't working or the results we were producing wasn't good enough. So that establishes that what we need to do is something else. It's likely that we had tried what we knew but even those efforts weren't successful. So, when we exhaust what we know, all that is left if to try something new.
Second, let's rationalize the change itself by ensuring that the change is not really a total change, that we are not changing for change's sake. In fact, the best change we can do is to build on our experiences. One of the main concerns about doing something new is failing to achieve what did work before. There are two ways we can make sure when we try something new, we achieve at least some success. First, we must know what success looks like. We need to list down what that something new must achieve. We must define the goals so that whatever new things we do, it's headed in the right direction.
Second, we must also list what needs to be done other than the main goals. Even though what we did before didn't work out, it probably still did some things that were necessary. Like reports that needed to be generated along the way or measurements that needed to be taken for quality purposes. Sometimes, our previous efforts did something that was required for something else to work or necessary for another group's success. By running through what we did before and taking note of the necessary steps or things we need to produce along the way, we are ensuring the change we are achieving by doing something new still hit key targets along the way.

However, this does not mean that the goals should be sacrificed in place of necessary steps and intermediate targets. By doing somethings new, we have to accept that some steps and targets will have to be changed. The main point is that we achieve our goals. Even that is subject for change. Perhaps we need to split the effort and achieve some of the goals through some other process. This line of thinking has to be taken into consideration when solving problems. Step3 allows us the opportunity to split goals into different processes or solutions. Perhaps the solutions available to us does not achieve all the goals we set out. So, we should note which goals are effected and start another process to address them, either by doing something else with a different context or determine whether another existing process can be expanded to achieve those goals.
When assessing which of the candidate solutions is the best, we may need to note what intermediate targets and steps are not addressed. Determine whether the targets can be ignored or steps can be skipped and address those individually later. By keeping the goal in mind, we have a better chance of choosing the best solution. And that disruptive change we achieve is just simply success.
