When I first started lifting weights regularly, there were plenty of days I did not want to go to the gym at all - days I felt sick, days I felt tired, days I was down in the dumps. But I made myself go anyway, because I had committed myself to it, and I knew that if I started skipping days at the gym, I'd skip more and more, and whatever gains I actually made would be slow and, likely, negligible.
So, I went, time and again, when I did not want to go at all. The feeling after was always triumphant - I had vanquished my emotions and managed to achieve in spite of myself. And six months after I'd begun working out three times a week, every week, I was back in front of a bunch of my old colleagues, and everyone was impressed at how much muscle I'd put on.
I hadn't even realized; because I saw myself in the mirror every day, I hadn't seen the transformation. All I'd seen was that I kept lifting heavier and heavier amounts of weight.
Going out to meet women is just like this; the important thing is not being "ready" to go out and meet women - the important thing is going out and meeting women.
But a lot of men have trouble doing this.
