Haha, I'm only a student! However, if you really, truly love the subject, go for it. It's a lot of work, and a lot of the biologists I've seen and worked with during my time as a student have been very happy with their careers. But it's a huge time commitment, and like any science you can choose to study, it sucks a bit of your soul out at some points from the workload. Definitely do your homework before you jump into university studies, although that applies to any field, really. Best of luck!
