Depending on the context, "I have to find a way to clear my mind. I wish I could defrag, hit the delete button or install a spam blocker. It is just not that easy."

     Could be about the many toxic thinkings, plans, to-do lists, resolutions, appoitments, everything  that we could say no to, but we said yes to them.      And there´s a time in wich the push comes to shove, then we wish we had find a way to rid our messy mind of these "junks" .    Keeping the essential, we gather speed in our decisions and become more carefreee.

      That is, poderia ser "Eu tenho que (re)organizar minha cabeça/mente; eliminando o não essencial, o lixo, apagar lembranças doídas, experiências que me "travam" , enfim tudo que me atrasa o meu funcionamento...ou da minha vida"

     Not a plain translation, but that´s the idea.
