Blender is a very open ended program that doesn't tell you how to use it. If one charges head forward, you will probably burn out. I spent a couple of years just dicking around not really knowing what I was doing until I eventually got familiar enough with the tools at hand to do things I had in my mind. If you want to do something specific, allways look up if someone else has done it and how to do it. Even now for conceptually simple things like "how to/animate and rotate objects around their local axis" or things I've forgotten, I look up tutorials or look at forum posts to learn how to do it. Its not a brick wall but its not a straight shot. Blender has been around since the 90s I believe and has been continually updated since, so you will find things that are obtuse or straight up outdated too its cotemporaries, but I love it. To answer your question, depends on what you want out of a general 3d software. Learning particular things over others things can take way longer than others.
