make your own samples, delete them after you use them. that is, if you want to be creating. or at the very least, find your own samples. not saying this to be a dick. im saying this because if you want to write stuff that works with inspiration and creating something fresh in mind, instead of making music that sounds like what many people have already done..well, anyone would be best off doing their own sampling.
its fun (and you learn a lot from sampling that you can apply to things like mixing/mastering), and it derives creativity from what you hear in your own head. saying 'man, i wish i had a sample of that', well, if you're wishing it, then you can just as easily make it or invest the time into finding it if you cant. using sounds that other people have already used and used again countless times before makes derivative music and leaves little or nothing for the listener, or at the very least, leaves it up to the author's songwriting ability. if they're into a wide enough range of music, the listener has already heard a lot of what you would already want to use anyway. the only argument i can see against this is that people want to make something thats accessible, and that begins a downward spiral of writing music for the wrong reasons.
think about it: if you give people your samples that you've already used in music or that you sampled from other music, are they going to get into the habit of making their own shit? no, they're gonna continue to be reliant on people either giving them samples, or using what they are able to find. its kind of why we have abominations of sound like trap and dubstep now. you want to encourage people to make their own sounds no matter what.
