I can't imagine not having someone to share my life with. I can't imagine coming home and being alone.
There was a time when I thought nothing of it. I had weekends where I wouldn't speak to anyone. Worse, I remember days when I'd find myself talking to myself and being surprised at the sound of my voice.
I remember a time when I thought I was totally alone; when I questioned whether anyone even existed.
Now I know better. I know that without someone (or even something) to share the highs and lows of my life with it is meaningless. And I do not believe that I was put here with no purpose or meaning.
I have a wife. Spending time with here has been the best choice I have ever made. Almost every good day that has happened to me since I met her has been related to her. She is a joy to me.
Do you want to have a good day? Find someone to share your life with. Find someone that will share their life with you. Start small if you have to, maybe a cat or dog. Perhaps you'd feel more comfortable with a family member and Facebook.
It doesn't matter how you start. It matter THAT you start. It matters that you go out and share every day.
Do you want to have a good day? Open yourself and share who you are.
[Also . . get a wife. Wives are amazing and I cannot recommend them enough. (mine is taken though . . find your own.)]
