I think another way to look at is is anti-social with the opposite sex by choice. Some people completely turn off their radar by not socializing with those of the opposite sex in order to avoid being smitten. But, sometimes there's not enough self-restraint in the world to hold someone back when they meet someone who makes them feel better than they've ever felt before.
Though, thinking like this can also come with a cost. When does one decide its time to let their guard down and roll with the punches? What if success or financial security comes late or never comes at all? Is being too cautious with ones goals worth missing out on a golden opportunity when it lands in their lap (love)?
I'm reminded of the age old question, what's more important? The destination or the journey? Is it wrong to allow love into ones life while maintaining a stalwart position with one's goals?
