Go to a charity shop and buy loads of music you have never heard before and go home and listen to it, then take all the quiet bits out of all the songs - even a really, really, shitty CD or record will have at least one two or three second noise that NOBODY has ever sampled before. Do the same with crappy old movies, soundtracks, film scores - especially for films you have never seen or will probably not enjoy. Try shitty old chick flicks, listen carefully to awful solo albums made by members of girl bands long after they stopped being famous.
Take all the samples you find and put them into folders.
Repeat this every week until you have hundreds of sounds that nobody else has ever bothered to sample
Then start fucking about with those sounds . Trim them, saturate them, layer them, resample them.
You now sound distinctive and unique and are not using the same sounds as anyone else.
What you do next is entirely up to you.
This approach has worked for all the people that all the people you rate look up to throughout the history of Jungle and Drum and Bass.
