> HOW DO PEOPLE NOT STEP-STEP-STEP
I think I have felt some of what you are feeling.
The debugger is ... seductive (: For one thing, it is an educational experience, as you step along you are learning what your program is actually doing, which is a good mental checkpoint, especially when I was a more junior developer. I think a debugger as an educational tool is a big point in its favor. And so you may develop a positive relationship with your debugger, and want to bring it with you wherever you go.
But you may find, as I did, that the sparkle of that relationship fades somewhat in time. You will be better at knowing what the code does, without needing the debugger to tell you. You will hit situations where the debugger cannot help you, or is less helpful than the alternatives. You will get better at structuring your code so certain classes of problems simply don't happen as much, rather than using a debugger to peek-and-poke to fix things all the time. You may find the debugger to be a relatively exhausting high-touch real-time experience, compared to thinking about issues more at your leisure, or getting a larger understanding from other sources.
And so, with experience, and hopefully with an open mind, the debugger will settle into its proper station, in the pantheon of your various debugging aids. Not bad, but not the end-all-be-all either.
I am being somewhat flowery in my language, but all I am saying is: it's okay to rely on the debugger, at some stages. Give it time. Just don't forget about the alternatives or denigrate them needlessly. You want to build a big happy family of technologies and techniques (many of them residing solely in your mind) that can all work together.
