Hi there! Welcome to the forum, first of all
I can't say I'm an expert to be saying, I am just in a course myself and only been there a month so all say is really my own experiences and sharing some of the thoughts from my classmates on the topics but I hope that it helps you all the same!
In terms of stability - people in my class I have 2-3 who did massage before but wanting to refresh themselves and they reckoned it was pretty stable albeit they found being self employed a little tricky (though this can be affected by many factors including location/demand). However a lot of them agree that having a certificate into Sports Massage will put them in a better position for a job (presuming to be employed by someone) than what it is for someone who doesn't. Equally; over the past few years I've noticed a lot of demand in places such as cruise ships which mostly run on yearly contracts which can be renewed or not - for at least some grounding (and life!) experience that may also help =]
Consider: location, local demand (don't be scared, go into health spas, massage parlours etc in your area and ask!), what type of massage you want (sports, leisure, health) and also what qualifications will mean to you (are you going to be self employed/employee and which are the most in demand qualifications).
I think the second question rests somewhat on personal experiences and opinions. All I can say is being in a college (which of course will have bias in it, so how much truth, I couldn't say) is that learning through a body is more secure and professional to image than not. What I will say on that note though that I do trust in 100% is if you do go for being trained up via a spa then ensure of what the training in the end will get you. Will it be a recognised body or just a certificate from the spa? Again, if you know what you want to do with massage, it will help you understand what you will need qualification-wise.
As I said, I'm training and hand on heart, I love every single class (including Anatomy and Physiology though I'm sure it hates me

!) and it's hard work but extremely rewarding! The one thing I hate is trying to perfect going through a consultation form without sounding like I'm just listing off conditions and sounding too...clinical. But that's not really a thing with massage itself it's just my own frustration to master a technique!
Hope it helps!
