<prompt> Human: Hi, I recently got a job offer making 40k more than my current salary bringing me to 150k in Silicon Valley. I like my current company and they have indicated that I will be promoted during the next performance cycle, October timeframe, bringing me to a similar salary. But there is no guarantee. I would feel bad leaving them, it is a top 4 consulting firm and Ive only been there two years. However with an MBA and 8 years of experience I feel I am being low balled but like the idea of sticking with them. The company giving me the offer is smaller and operates much differently than the larger company I am with. Kind of on the fence with this decision and looking for input. 20k in student loans, only debt and no kids. Let me know what you would do or any advice!  <response>: Change jobs and take the guaranteed extra money.
