How do you like being a scientist? Would you recommend this career path?

I enjoy scientific research a lot! But I would only recommend this career to really motivated, hard working people with some talent. Being in academia comes with a lot of costs. The job (not well-paid) competition is fierce and the progresses of other aspects of life likely will be delayed (on average). Quit and switch early and do not procrastinate until one is trapped. My opinion is that more selective, much fewer graduate student entry and much better compensation to postdocs and staff scientists will make the environment healthier.
