I suppose it can be a result of me thinking of my career and what I can achieve by what actions. And, probably, I can admit that I am not as hot these days about making others' dreams coming true rather than some my dream, which makes me not so passionate about spending 12 hours a day to deliver some code.

These days in relations with the employer I think more about having a balance between what I get and what I give, rather than hoping for the boss to notice me and rewarding me a high position or an equity.

This allows me to plan how much income I can put aside in order to eventually start my own product/business.

By asking your question you made me to sit for quite a long time and think about that "other reason", it's quite insightful, thanks!
