OK...your first step is to stop telling yourself you can't do stuff. That will keep your life ****ty forever.
Game has almost NOTHINg to do with your car, your house, your job, or your skin color.
Game is almost entirely to do with attitude to yourself and your life.
At the moment your attitude sucks. You sound like a whiney crybaby making excuses. That is not attractive to anyone, women and future employers included.
Job first- if you like people have you thought about nursing, the police force, teaching, personal instructor, lot any of the dozen careers that involve working with people and not in sales.
Self-improvement. Lots of guys on here talk about going to the gym, lifting weights and stuff. It is good advice. Gyms are expensive, but fitness isn't. The main benefit of this stuff is not because it makes you look better, although that doesn't hurt.
The main benefit is you feel better about yourself. The better you feel about yourself, the more confident you feel, the more confident you are, the more attractive you are, the more attractive you are, the more successful you will be in all areas of your life.
Confidence is about setting goals for yourself and working to achieve them.
Confidence is about believing you have value.
Confidence is about having the power to make choices about your life. I know it seems as if sometimes we don't have choices but that is bull****. Everyday I get out of bed I have made a choice. Every day I choose to have a subway instead of a burger and fries I am making a choice. Every time I stop myself from making a negative comment about myself I am making a choice.
Bad news though for a young guy like yourself. Women are not the goal. If you have a life you like and are a person you like you will get women.
There is good news, you don't have to be gorgeous, rich, young or buff to get laid a lot although all that stuff will help. I am too tall, not glamorous, rich, handsome (IMVHO), too old (46) and I only improved my game in the last year. Now I have two FWB who are desperate to **** and several others orbiting who are also keen. One of them also wants to be my sex slave. I am not bragging (much) I am just pointing out what is possible. I didnt get buff or rich or anything or get plastic surgery.
I changed how I looked at myself.
I started to like myself, I started to realise even if I am not handsome SFW, I can still be sexy. I also let myself be more sexual with women, holding eye contact and touching more. I also learned that having the power to say no to women and letting them know they can leave any time they want will not bother me that much, put me in control and gave me the choices.
TL
R. Women don't like losers. Learn to like yourself. Take control of your life, one small choice at a time.
Be confident. Make eye contact. Touch more.
Good luck
