I know that I have mess in my life I have to clean up and am doing so. I believe that a lot of us do. My hair may be messy however what is more important is that I clean up myself on the inside. The mess of the way we think in a negative way or had bad habits.
By working on myself and my mindset I have been able to improve myself and hence be a better person, clean up and be a better and stronger person. This is more important than have messy hair day or all the time even.
So be the stronger person, change your mindset and be the best version of you.
