This is a nice problem to have, so find some comfort in that. Personally, I have felt that in situations like these I usually know what's better but I just don't know it when I am confused and just keep thinking about the options. So how to get rid of the confusion? Sit down and relax and then WRITE IT DOWN. Make a table. You are looking for 2 things - What are you gaining and what are you missing out on - by working at Google and by doing your own startup. Think thoroughly and write everything down. Once you have laid down everything you can think of, leave the notes. Get back to them after a few hours or even the next day (Meanwhile you may keep thinking about some of the things you wrote, that's ok). Then review with a heavy focus on the 'what are you missing out on' column and TADA! If you are honest with yourself, you should have your answer. Wish you all the best with whichever option you go with. Don't forget to update the thread with your decision and why you went ahead with it. Who knows it may probably help someone down the line.
