I started working for my current company about a year back, and I was given ownership and the freedom to develop my work which I found very lacking in my previous company. I took this opportunity to learn a lot, I took ownership, and I started doing things that were not in the pipeline in my free time that would benefit the company. I was really happy with what I had built, and I was rewarded for my work. I was happy! That was nearly six months ago. Now, working at the same company I am not very happy, probably because of burnout, lack of senior developers or decrease in the learning rate or possibly because of how confused I am right now. Professional life can bring you happiness, but I am doubtful if it can do that for a very long time. It's always the personal life that determines how happy you are.
