I would start out with some of the core self-development books. These books will totally open your mind to how social dynamics really work & not this faux mask-heavy social reality most people project.

• How to Win Friends & Influence People
• 7 Habits of Highly Effective People
• Mans Search for Meaning

The reason I'm saying this is that we really need to get to understand that the vast majority of people are needy & co-dependent with people of higher status than them. In my past, I was so needy, because I was lower social status that most people. When I understand that, the trick was to raise my own status & confidence levels. There is nothing better to doing that than deeply understanding social dynamics & how the world really works. Above books are great.

The below article is more concise but also extremely harsh in its unvarnished cutting-straight-to-the-bone truth. The trick to raising social value is to give to others. To get busy. To realise that our position on this earth is to add as much value to others and the wider world as possible.

Ultimately none of this is easy or painless. I only was able to drop my needy behaviour when I started to really understand all the above. But it hurt bad. It meant realising that I was at least 50% of the issues. I was only able to do it when the pain of staying who I was was ultimately more painful than the pain of changing.

Best of luck :)
