Hi. I seem to be spending my saturday night helping people on a message board, so maybe I'm not the best person to get advice from.
But I'll try to help.
"I am about 30 lb overweight and that's the reason why I haven't been able to get any girls."
No it's not.
Look, you are starting from the bottom, and the problem is, for starters, that you're going to want quick fixes.
I know the feeling. It's like you're going around looking for little shots in the arm, little boosts. A compliment. A video game. Bragging.
You're living in a persona right now, and your persona isn't serving your confidence.
You have a lot to learn and it's going to take time.
Committ right now to taking a SIX MONTHS to fix this, and don't expect any RESULTS for those six months other than constant self improvement.
During this period don't expect to get any women. If you do, fine, but if not, then whatever.
Now, with that out of the way, I want you to do something really stupid that's going to help you get out of your persona, because it's holding you back from experiencing life, and that's holding you back from women.
Turn off any major lights in your room, maybe just leave a night light on. Relax.
Just let thoughts flow in and out without much concern for their contents.
Now take five or ten minutes and explore your room, OBSERVE everything in it, every little detail.
Look at your door. Is it wooden? Examine every particle of it. Your computer. Bed. Everything. Experience all of it, every little detail like you never have before.
No, you won't get women by doing creepy things like this

The purpose of doing this fruity exercise is to ground your experience in reality and out of your HEAD.
Your head is messing with you right now, and you need to just drop all of that bullsh*t swirling around in there. This will help.
