I don't recommend a life sciences degree unless you are pursuing a Ph.D. - if you want to work in the life science field, that is.
I wouldn't pursue a life sciences degree unless you are planning on completing a masters. Many people become disinfranchised because they don't get good life science jobs with a BS, and honestly, it's not the system that's failed them. The system is set up for reasons. A BS creates a scientist on an introductory, binge and purge level, and they've not been trained to think for themselves as scientists. That happens in a masters program.
As far as a bachelors... Suck it up and get it done. Most of your classes will have very little to do with job training, most all of them have to do with learning "life" and time management. Don't wait around, it's too tempting to not start. It's just something you have to do. No one expects someone with a bachelors to do much of anything (including business majors) until they've had time to age and gain experience (ever wonder why Pharmacy is a 6 year program? They expect a great deal from them!). So NEVER feel tied to your bachelors major, like that's the end of your life story (unless entering pharmacy heehee).
A masters program is NOT for everyone at 22 or 23 years of age. There are some who know what they want at 18, but that's few and far between. For people that aren't that type (ie the rest of us

), and are looking into the natural sciences, there are hordes of seasonal jobs all over the United States and Canada (not to mention abroad) for people who are willing to work hard for little, but get paid in some of the most beautiful sunsets in the world. You can find jobs like this through organizations like the Nature Conservancy, State and Fed agencies or even look into Americorps. And you are IN the field, watching biology and ecology happen.
I think this is a great opportunity to seize, and you will learn so much about the world and yourself. I could have seriously benefit by throwing off the saftey belt. And I would have never had to take the $65k pay cut going back to school from my financially secure, private HELL I spent in the Corporate world doing business with my bachelor's degree in Biology. However, I can tell you the sacrifice is worth every penny of debt I've now incurred to manage the financial roadbumps in this major life change.
If you go this route (the "I'm not ready for grad school, what can I do?" route)... You may think the best thing that ever happened to you was that you ended up managing streams in the short grass prairie region, and you can't think of anything else you'd rather do (a win). - OR - There's no way you want to be doing that crap when you're 45, so you go back to school and learn how to think and communicate as other scientists think and communicate (a win).
Then you might find there's all sorts of questions you want to examine, and get sucked into a research degree. I'll be 40 before I have a "career" now, I didn't intend to do a PhD. But I get to live my work in the meantime
