I would like to pitch in, if I may. I'm also homebrewing and have brewed 50 batches until now. I started January 2017. I am now 34 and plan on brewing even more, maybe starting my own brewery at some point.
I have never brewed a recipe I found on the Internet or from books. Actually, I have not read any books, but did and still do research on the Internet and talk with other brewers ( also commercial ones, once in a while ). All my recipes have been original recipes I've designed myself, starting from general and specific recipes for the styles I was brewing and from reading guidelines, experiences and much more, related to these styles. I've never experienced any infections, gushers, bottle bombs, etc. I was probably lucky.
I however brewed beers that did quite turn out how I expected, but I've learnt from these and then tried better next time. But at the same time, I've brewed really good beers, which others have tried and gave very positive feedback.
I also do not repeat the same recipes. I like to experiment and brew as much as I can. For me, it's also practice before - possibly - taking the leap to commercial brewing.
I will say, that designing your own recipes and brewing those beers, is a lot of fun. It's also challenging and will probably get you even more pumped-up for the results.
At least this is how I feel every time I brew and wait for the beer to be ready.
