People tend to really like doing things that give them meaning. Meaning is derived, generally, by progress towards a (Well-chosen) goal, and being at the edge between chaos and order.
The convenient thing is, that this progression that gives life meaning is the very thing that helps economically. If you find hard mathematics frustrating, then there is more chaos in it than you can withstand. That likely has to do with IQ, true, but it doesn't mean you're mathematically useless, it just means that you have to pick the application of mathematics that fits it's meaningful development without spoiling it.
If you want to get great at something, competing is often a good way to do that. The job market is just another kind of competition. Pick your goal to be reachable, but more than you are able to do at this moment.
