I've graduated high school and I am joining college soon. The problem with me is that I'm not finding less tangible math interesting at all.
Some people find abstract math to be very beautiful, and I'm exactly the polar opposite. I am turned off by seemingly pointless abstract mathematical structures with no use whatsoever. For example, some people find group theory to be very interesting after learning the definition of a nilpotent group; I couldn't care less as I never got why would someone make those weird definitions in the first place.
I have found that I will find a topic to be (very) interesting iff that has mathematical "real-life"/concrete/tangible/physics related applications (e.g., proving isoperimetric inequality using Fourier Analysis or Prime number theorem with complex analysis). But to be able to appreciate how that theory relates to the more concrete applications (e.g., understanding the proof of PNT with complex analysis), I need to navigate through the material I find "boring", which turns me off since if an exposition of the topic doesn't routinely provide examples of such concrete applications, I get bored very quickly.
For example, currently I'm now working my way through Stein and Shakarchi, Complex Analysis and Stein and Shakarchi, Fourier Analysis. What really intrigued me at first is that you can prove really cool number theoretic result with complex + fourier analysis and motivate the Olympiad coloring proofs (see this link for the details of what I mean by this) with discrete fourier analysis. So when I started reading I was very interested and breezed through the first few chapters (Chapters 1,2,3 in both books). But now I'm on the section "The action of Fourier transform on F" and I find the chapter to be too much boring so I am now feeling disinterested.
So, math educators: What are some tricks/strategies to keep students like me motivated with the material even when it feels less tangible to me?
PS: It's not that I have problem with understanding the material. In the chapters I read in SS, I didn't face any difficulty with any of the exercises/unstarred problems (though I did face lots of difficulty with starred problems.)
