I am a scientist. My job is to do numerous experiments to test hypotheses. Everyday, I wish my experiments work, wish them work out as what I planned. However, chances for those wishes coming true are so slim. By the end of day, frustration and sense of failure hover around your head. How can I make my dream come true? How can I make a step forward towards my career goal? Self-doubt is ensuing. Should I make career adjustment? Tons of questions take over my head.
The worst situation is your life partner is in the same boat. I often keep the frustration and mental battle to myself. If I have any sort of financial backup, for example, my partner can support the family on his own, I would refuel myself in classrooms and change the way I am living my life now. This will bring about a better life to myself and my family, make a virtuous cycle. However, the very single variable can not initiate this cycle. So my life can only run as it is now.
Of course, many people think it is perfectly fine to live the life as it is, or even over joyed with the current situation, for instance, my partner. To me, it is dangerous to be content with current state for you will lose the motivation to make progress in the life.
