I started in this industry at a time where most people had no degree...either from just not bothering or 'dropping out'. Degrees became a little more the norm over time and as such there came to be a point along my path where most people new to the industry did have a degree and I was largely surrounded by quite a lot of 'qualified competition'.
i.e. I've been through this.
As a result, I spent many a year around that time wondering whether to get a degree or not. I never did take the leap and nowadays I’m glad about that, as the time would have been wasted. The only thing that really mattered was that I was always able to do the work and after years of doing that, the relevance of a degree that I might have taken time to earn 10, 15 or 20 years ago is just obsolete. Nobody really cares nowadays and for the most part never legitimately did, either I just have much more experience than most people around me which nullifies their issue or, they have enough experience in addition to their degree to now understand it doesn’t matter. Stick with it and you will find yourself in the same position.
People can be a judgmental as they wish but if you can do the work they will never have a legitimate complaint so please bear in mind that this speaks more of them, than any failure of your own.
Thus, I agree…if you do get it, do so because it adds to your skillset and not to get a +1 in the eyes of your shallow colleagues.
I would also add, the best +1 you’ll get is working with them and holding your own, especially if they ever struggle on something and you can help them out. This will serve as experience on their part and help them overcome their issue. Resist the old ‘well, look where your fancy bit of paper got you’ dance either way because that will just distract such people from appreciating your own efforts.
