One of the life lessons I can give you is that you can never predict the future by just thinking about it.
I would have never predicted that I could ever reach the place I am now. It would have been impossible for me to meet such amazing people if I had kept doing a 9-to-5 job. Going on paths not taken will be challenging, but one should never lose hope. Your passion might start getting boring, and it may not excite you as it used to. But it requires dedication to achieve your goals.
