Alright... I would be yourself... but.. if you are clingy and submissive and too nice you have an uphill battle. Women want some level of assertiveness from a guy who knows what they want in life. That's for starters. Don't be a pushover, and don't let her push you around when you know she is wrong or acting selfish. If she does not love you, kick her to the curb. Don't think you will make her love you some day, it's not gonna work. If she acts dismissive towards you constantly and is out with friends at all hours of the night, it's a warning sign.

If you are obese, lose the weight. There's no excuse here on this one. Eat less calories in a day. Just do it. Eat less carbs, and start exercising. Period.

Having a good paying job helps, and is essential if you don't have a cocky sense of humor. If you have a cocky sense of humor, and a naughty one at that, it's easy to get women for sex, you don't really need a good job then. Some people are good at this, some people are not. It will help if you are not overweight. Sex comes easy to people who talk naughty. Women eat that shit up, at least a lot of them do (not the type I would marry though)

After that you have to be careful and get to know her well, especially if she likes to go out clubbing, has a large social circle, and likes to gossip. These women are harder to please for guys not interested in that sort of thing. They are always trying to compete with each other for the 'best' man, and tend to be more on the shallow and superficial side.

Make sure you share common interests. Likes attract. Maybe she likes animals, or likes to go hiking in pretty areas, that sort of thing.

If you are thin, make sure she's not the type that will sit around all day watching soaps and let herself go. Honestly as a man it's not hard to keep the house clean. It takes maybe 10 minutes to do the dishes, and not long to do the laundry and pick up a few items. If people are that lazy that they can't even clean up after themselves, that's a warning sign they are just going to be lazy in general. If you are not lazy, avoid them. It will be hard to change this behavior and they will resent you and just do the opposite as a way of rebelling and expressing their individuality.

Use personal ads, but if they are deceptive in any way about themselves, don't be afraid to tell them off. For example if they list themselves as 'average' weight when they clearly are not. Honesty is essential. Put yourself out there. For the most part, women do not ask out men, the men have to do the work. It's a numbers game. Go to places where women your type might gather. Library, Petco, Humane Society, whatever.

Spend less time thinking and more time doing. The time you spend thinking about how you can't get a woman could be spent asking them out. The time people spend thinking about how they don't want to do this or that housework, they could just do it and it would be done. Don't be a slave to your programming. Change your mind and act on the changes. Don't be a sheep to your habitual programming. Try to use conscious willpower to change your habitual programming and break out of your 'rut'
Alright I'm done typing, I could type more but meh...
