I am trying to get into window washing but I don't really know where to begin. What are the most profitable aspects of this career path. Do I just do window washing or do I try to get into repairs and replacement and all that too?

Since you're a newbie you might want to try to just get the technique and making your own business out of it and advertising it a bit. Later you will find out much more about how things are done once you have experience, if anything at first you'd need to knowledge and skill to actually be able to clean windows properly and to advertise properly. For now, try to train yourself for that.

Well to tell you my story I'm not really experienced in all of that just the first part and currently I am doing fine, lately I've started learning new things and as a newbie I found them fulfilling since I'll be able to earn more

just wait it out and stick with it you'll see it's not that hard or anything
