- If you don't actually like sales and feel comfortable in it then the stress is going to grind you and your life down into less than what you were before you took the job (I personally am never going into sales again unless it's that or the gutter)
- The more of a psychopath you are and the more you can shut down your own feelings/sympathy, the better you'll do. Being in sales dehumanises your interactions with people after a while more so than other people-oriented jobs because your job is a direct extension of our civilisation's basic drive: to exploit people as much as possible
- Don't take what your boss(es) say too seriously. Your job is to sell a product to customers, their job is to sell being a salesman to you and keep you from f*cking up their company (example, bosses will tell you to not do things like screw customers over - the real message is to not do it unless you know how to get away with it). That you can theoretically become financially independent and such is part of the portfolio to draw you into being a salesman and it illustrates something pretty well - selling customers your stuff without them feeling like they're actually being manipulated
I think the "you either are a salesman or you're not" trope is actually truer than I tried to deny it was back when I still was one. It's not that you can't learn to be one, it's whether you authentically are predisposed to and like being a salesman. So when you start out, listen to yourself. Is this what you want to do? is this who you want to be? the thing with sales is you won't just be miserable if the answers to those questions are no, the stress will destroy you too
Thought I'd provide a voice of reason to what I suspect is going to be a continuation of posts telling you to go for it, which I'm not necessarily saying you shouldn't, just don't destroy yourself over it.
