Well, a mathematics degree is one of the highest income earners for a reason so its usefulness is beyond dispute. I personally have life and artistic goals which take priority of my time over math but I’m willing to allow mathematics (together with high-level scientific understanding) a place in my life as a tertiary goal or drive. We are all a little too hard on ourselves to get everything done before we turn 30 or 40 as though it were some kind of deadline and then why bother, right?

If you find pure math interesting then give yourself the slack to learn it long term. Think of it like a rock garden which you tend to over the years.
