Life is way too short to be at war with yourself.
Sometimes we can be our own worst enemy. I know I can be. For example, I'll see a single attractive woman on the train on my way to or from work or downtown somewhere, and I will automatically convince myself of failure. As a result, if I'm not with friends who will push me, I won't even make an attempt (sometimes I will, just not all the time). And then I'll be angry with myself afterwards for not trying.
So, I'm going to make a promise right now, right this minute, to approach the next attractive woman I see. The worse thing she could say is no, right?
Have a blessed week!
