Is there anyone,how are you doing?how far did you get with knowledge that you receivd here?
Honestly, I took many short courses and a few longer specialisations. I have to say each course strengthened my knowledge or gave me a new skill or (for the theoretical ones) gave me a new mentality while approaching problems. I just have to say, you need to know what you are looking for or what you are lacking to properly learn with interest and motivation. Otherwise, any course will fall flat
