<human>: I'm in the consulting business. I've been with my company over 6 years, and was one of the first handful of employees of the firm, and have seen it grow exponentially. My salary is nice ($130k), I am super secure in my job, and it is very comfortable and stress free, and allows me to basically coast without too much effort. The company has historically made promises (equity stake) that haven't come true, and while I really hope they will, somewhere inside of me tells me that ship has sailed and if I stay, I can just continue coasting, albeit a very comfortable salary and work that is really not hard or stressful, and should forget about those additional promises.

Along comes company X, they see my skills and talents and want to hire me desperately. They are willing to pay me 15% more, with perhaps additional incentives as well, and less work travel. This position is more prestigious that my current one, for a larger company, and offers more career growth opportunities ahead, and along with that a lot more challenges, stress, and risks.

On one hand, in my past I have always been a risk taker and risen to challenges, but I've also been the type of person who hasn't truly had to work hard to be successful... On the other hand, now I'm having some anxiety about walking away from a good position that already pays well and has little to no stress, but may not offer any further career acceleration and leaves me hoping they fulfill those promises someday.

Is this anxiety normal? Is this one of those things I need to do if I really want to foster some real career growth and push further? Any advice? Is it maybe I'm so used to not working 'hard' that the thought of hard work again has somehow got the best of me in the meantime?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Should I leave a VERY comfortable position for one with higher pay, more long-term career growth options, but more stress and risks too?
