Girlfriend is a go getter, I’m more laid back, help?

My girlfriend who is 22 is a go getter, self employed and motivated. She has big goals and looks like she will work her *** off to achieve them. It’s just naturally in her and she’s started off since she was young.

I’m 26, more laid back and not so motivated. My best friend is very similar to my girlfriend and he’s been trying to motivate me to do this business with him and earn more money and have a better life in the future. I’ve jumped on board and now I’m doing the business with him. 

I’m comparing myself to my girlfriend, and I feel like I’m behind in life.
I’m 4 and a half years older than her and I should really have my life sorted out but really I’m quite behind. She owns a house from the age of 21, she’s planning to start saving to buy her second house, and eventually wants to get a third so she can rent them all out and have good income coming in.

I feel like I hate myself because it’s naturally not in me and she’s got that drive in her whereas I don’t although I am now trying my hardest but I sometimes feel it’s not good enough.

I eventually want to buy a house and the idea of renting it out sounds appealing to me, but I find it a struggle because I need support and direction whereas she just knows what she’s doing.

How can I feel better about this? I also want our relationship to work well but this is my worry at the moment and I’m concerned it might get worse later if I don’t seriously pull up my weight but I’m struggling to find out how to?
