Present
I need to stop fixating on the past and the future, because the past is not there anymore, nor does the future exist right now. I need to think and feel what's already here right now, and what I can do at this very moment.
It's just pointless to do so, and I won't go anywhere if I keep up this habit. But it's difficult to completely be in the present right now. Which is why I need to train myself to be present and enjoy the natural pace and beauty of where I am.
No more dwelling, and no more overthinking. Just do what you want to do right here and now.
