Don't put all your eggs in one basket on the stock options. As @svisser pointed out, are you happy with the company, what you will be working on, your salary, and benefits. Those are immediate rewards for your work and matter most. At this point in the company's life, your options are more a formality than anything. Even if the company does go public, you are probably several years away from that happening, and who knows if you will still be at the company or still like the job. In addition, by that point you will have also probably (hopefully) received some additional grants along the way to even things out.
