Before we know it, life is one big mess. Why? Because we cannot predict life, therefore we need to change and adapt to it.
You cannot expect to do things the same way for the rest of your life and get different results. You cannot even do things the same way all your life and get the same results. That’s life.
What you can do however, is be flexible and adaptable to the changes that you know you will encounter along the way.
This won’t stop you from making goals and plans, what you need to be aware of, is that there are always lots of different ways to reach your end goal. If the planned route doesn’t work out, then look for another one.
