Yes, I think I do know you mean.
Prioritize your "sound" by that, I mean if (as an example) the music you hear inside seems in your mind to translate best thru "strings" make it a priority to acquire the best sounding string patches you can find. If it's percussion, focus on getting the 'real world" gear or finding a realistic sounding percussion software (and spend the time to learn all of it's nuances)- If vocals a primary focus, save up a little longer to get a better mic and pre-amp.
In short, don't cut corners and fall prey to instant gratification because something is "kinda close" and inexpensive
It may take you a little bit longer, but the ideas will still be there waiting, and having the right tools makes the task of translating from brainwaves to soundwaves much less frustrating!
..there's my philosophical rant for the the day!
