WP and Marvin should approach/view about getting women the same way they approach work/most things in life. I mean, say in a job, you rarely get your dream position/make CEO of a company straight away, unless its a family business etc. You usually have to start at the bottom and work your way up.
Think of this for getting women too.
Start off with some women that aren't particularly attractive/fat and probably have the same level of self esteem (maybe even less) than you do. This will help you build your confidence and you'll learn how to act around women. Gradually over time you can work your way higher up the "ladder" in terms of attractive women.
