IMO "I suck at subject X ..." simply means the amount of work/time you're going to need to invest to master subject X is larger (sometimes much larger) than folks who have a knack for it. It rarely means you're completely incapable of mastering subject X. The real question is: is the investment worth it? If it takes you 5 years to master basic linear algebra because your brain truly isn't wired for it, how much is the 5 years you are going to spend going to pay back in the long run? Oh, and: actually enjoying doing X is usually a tremendous help towards mastering it.
