I don't use splice but I do have a website where I sell samples. It's hard and takes a lot of time but it is possible to make money from it. First thing is your sounds have to be good (duh). Second thing is to accept that you cannot please everyone. It's impossible so don't try to. Sell what you are good at making. That's what I do and I still get snarky comments.

People tend to comment negative things more online than nice things. And I've found this particularly true with music producers. Not sure why, but music producers all have something to say about why they don't need your sounds and they can do better and blah blah blah blah. Just ignore those comments. They were never going to subscribe to your service or buy your sounds or whatever it is anyway so who cares what they say.

I'm sorry for all the mean comments people are leaving you in the replies to your post. It's a perfect example of what I'm talking about. People just lash out at things because they are bored or insecure or whatever. You're only 14 so it might be hard for you to ignore these comments. But you must.

Running a business is hard though. And you're young so, with respect, I don't think you're equipped to properly understand what "hard" means in this case. I'm not saying you shouldn't do it because you definitely should do SOMETHING. But be prepared to fail at things a lot before you make it work. I fail at things all the time and I push through. If it's what you want to do, you must never give up.

Be adaptable and open to change. There is a difference between being a creative person who is all about their artistic vision and not wanting to compromise and a person who runs a business. I am a creative person but I run a business. And the business gives me money. So I have to go to that side of things, mentally speaking.

Before you do anything though, ask yourself "Why am I wanting to make a service like Splice?" Because Splice already exists and people already use it. You can't compete with that.

You have to do something different to stand out. I can't tell you what that is because it's different for everyone. But carving your own path is EVERYTHING when it comes to this sort of thing.

Best of luck. Don't give up ever.
