As a newbie, I would love to know how it gets easier.
I'll tell you how and i'll try to be as succinct as possible. As you grow older you simply let go of all the hang ups you had as a younger person and have your **** together. When you were younger you were probably confused and likely did not know how to act around women and often got the WRONG advice from people who meant well.
As you grow older you begin to understand how human nature, and in this case, female nature tends to work and at this point you will generally have things going on in your life. That's really it - women like older guys because they have a purpose and are self sufficient and thus able to provide.
If it were possible to go back in time knowing what I know now I would've simply lived for myself more. I wasted a lot of time trying to get chicks that could've been spent doing other things. The time spent could've been used towards learning new skills that could've had a financial benefit, or even just personal satisfaction. Most of the time when I went out for the single purpose of meeting women nothing happened - it was when I wasn't trying, like let's say I was at college walking to one of my classes, I'd pass by some girl and make eye contact with her and she'd obviously want me to talk to her. This is generally how it happened - When I was a teenager/young adult I was under the impression it was supposed to be this elaborate process and you HAD to do X & Y in order to get Z. Looking back I realize it was not so - it's basically a matter of being in the right place at the right time, but of course if you make yourself as attractive as possible you will get more opportunity. That's another thing, as you get older you don't really don't try as hard because you come to the conclusion about what I just said.
It doesn't happen all the time but it's not uncommon for me to now meet really nice looking young 20 something year olds that like me and I thought I would've NEVER had the chance with when younger. I'm pretty decent looking but was very shy and lacked confidence when I was much younger - not taking enough risk and lacking confidence held me back for quite a while - this partly stemmed from me not doing the work (I should've hit the gym, taken a martial art much sooner, just generally be more involved with what was going at the time).
