We think we are complex individuals. In reality, we are simple individuals wrapped up in simplicity. We make things simple to believe and those things invariably become our complex reality But even the complex is really quite simple.
Anything that is complex is created from pieces of simple things. We can reverse engineer something complex, break it down into its component parts and processes, and strip it naked. It becomes rather simple. Change one part or process and it becomes something else. That is true about everything.
Change one thought, and it will change the trajectory of your day. Change the sequence of one gene, and it will change the trajectory of your life. Slow down or speed up a process, and it could change the outcome of whatever you are intending as the result.
Let this give you freedom! Nothing has to stay the way that it is. You can change one thing and it will alter the rest. Choose wisely. Keep it simple.
