Sometimes you are not going to feel great, I think when it's physical recharge your batteries, chill you can't be a pick up machine all the time.

If you have to be out for whatever reason, don't judge your night on your success with women judge it by having a good time whatever it is you enjoy at the time, that might even be listening to one of your friends talk and saying the odd thing.

As for work problems, you're out you're not at work you can't deal with that now so don't worry about it put it far from your mind, don't let it control you. Also if you let that get you down then you'll be in worse shape to deal with it later so going out and having a good time will actually help you deal with it because you will come back to it fresh, well maybe fresh is a bad choice of words if you have a hangover but you'll have forgotten about it.

As for the ex girlfriend it's time to move on she has and be happy for her if you broke up amicably you can go and play the field! If she was a bitch then why are you even giving her the time of day, she's not worth your time?

Tolle is ok but he goes a bit mental on the new ageness the main thrust is don't focus on past experiences, live in the now and be aware of your thought processes and learn which to ignore and which to keep (which I kind of mentioned in the work bit). I think he goes too far and puts too much emphasis on not thinking which if you fully went through with it might leave you a bit robot like but there is some good stuff in there just keep your wits about you (even though he tells you not too).

Anyway hope you're ok here's an internet hug *hug*
