Repeating mistakes to learn something new

Sometimes when dealing with problems, we find that we face the same problem again and again. If it is not the same, the problems are similar. And we do our best to solve it each time. It's worse if the same problem keeps recurring, even after we solved it a few times. If we do realize this, it's actually a good thing. We have noticed a pattern and realized that what we have been doing hasn't been working out. It's good because now we know for sure that we need to do something new to solve our problem.
Learning something new or learning to do something new usually comes at Step5. We have chosen a solution and that solution can be something totally new. Which is a good thing because we have established that if the problem keeps recurring and we keep on doing the same solution, that solution doesn't really solve the problem. So we have to deal not only with a new solution but learning to do something new. 
But how do we learn something new? I’m going to save that for another time. Why? Because the hardest thing to do is not learning something new but doing something new. If we think about it, we already have many things that we have learned but haven’t applied. We know so many things that we haven't tried out yet. So, we are going to first learn how to apply something we already learned. This is so that when we do learn something new, we can put it to work immediately.
Not just put it to work once. But adopt it as a new way of working. It’s much like learning English or any other language. You have to apply what you learn. Only then will we become better at it.
We can make doing something new easy to do by first doing what we did before. Do what we normally do before trying something new so that we can adopt new ways of working easier. To put it in another way, repeating our past actions or pattern can put us at ease before doing a new set of actions or new pattern of actions. That way, it'll be easier for us to transition to the new set of actions and pattern.
If we can't do what we normally do because it has permanent effects, like fixing a broken equipment, run through the steps that we normally do and predict the outcome. First be clear on the goal of our actions. List them clearly, separating the main goals versus the other things that are achieved along the way. Pretend to fix that broken equipment for example, and every step, note what would normally happen or things that we would normally observe. If it helps, work this out with another person. They may provide feedback to our planned actions. Plus, when we say what we are going to do, our brain processes the problem differently. Now we have a list of steps that we did before, what we expect to happen and what we would do along the way.
Then, go ahead and apply the lessons learned. Do that something new or apply the new thing we learned. We have the goals to achieve. Make sure at each step, we move closer to those goals. We also know what needs to be done along the way. Make sure those things are done, too. For example, when fixing the broken equipment, we need to inform another group of people that their equipment needs to be stopped at some point for us to continue fixing our equipment. Or take note of the reports that the old method generated and what the reports were used for. Then we can find where in our new set of actions, those same reports will be generated or whether we need to use them at all. In the end, we will know what we need to do for both the old and new ways.
