I always seem to live in the moment. Whatever I'm currently feeling is what my life and the world is like.
Every day I have spouts of anger, depression, laughter, happiness, insanity, contemplation and countless other things. And for that moment, that's what it's all like. One moment I'm angry and depressed and the whole world is this terrible, raging, miserable place. Another moment I feel humorous and light-hearted, and the whole world is beautiful and absurd. Life is a song.
But at least at some point, I have a moment of self-reflection where I look at where I'm at and where I'm going. Over the past year or so, that moment has become much more peaceful and optimistic. I can list off the things I've done and what I've improved about myself and my life, and I can smile. I think that's happiness. Always have something to look forward to, and always accepting your current situation and that it's just that, a moment. Enjoy it for what it is and realize it will pass.
