I suck at math. Like. Really suck. I used to be really good at it at some point, but then I lost interest. So now, it's one of the things I suck at the most. I'm good at is geometry, I think. But that's about it.
Maths has always been my worst subject probably due to my lack of interest in it. When I put my mind to it I can do it. I usually forget it after I've learnt it and can't remember and need to relearn it again. Maths is always a roller coaster with me one minute I pass the tests the next I fail more often I fail. I just don't enjoy maths at all if I don't like something it's difficult for me to put any effort into it. I failed my last maths module on my course and now repeating it in my new course. Most lecturers/teachers tend to just explain it to you for ages just giving you example notes with maybe a few practice classes I usually get very bored in maths classes. Find X find Y etc...
Despite hating maths I'm actually pretty good at accounting I prefer that it's more practical to me.
To be honest, I do not think I am a real beast at maths. I sure have been on an "elite" programme in France but I think I am more of an "alchemist" with mathematics than a true mathematician. I must explain to myself mathematics in an odd way and I am terrible at learning by heart. So I am certainly a lot better than the average guy in this field but I cannot compete with true majors in that field.
As a data scientist, I think I use an engineer - even craftsman - approach to mathematics. I am bored by theoritical things you must take into account to validate your data and so on. I go more with guts, visuals, pragmatic and instinctive approach...and that works fine in fact for many fields I work on : forecast, optimization, etc.
I likre mathematics but more as a funny puzzle, tool and - mostly - ultimate business model framework. I love building massive things with it.
