You're Late, But Not Far
Most things have already been done, most ideas you've had have already been done by someone more faster and skillful than you. You need to realize that whatever new idea you have, someone most likely has done it, and probably has done it better than you'd ever do it.
Here's the thing, you're late. Pure and simple. Most things have already been done, most ideas you've had have already been done by someone more faster and skillful than you. You need to realize that whatever new idea you have, someone most likely has done it, and probably has done it better than you'd ever do it.
You need to undergo a set of demoralizing ideologies before you can actually start producing meaningful content in the world. This applies to everything, especially to things that can benefit other people. Usually, you'd want to be positive about most things; however, you cannot be positive if you have not seen or heard about the ugly. This is what will be able to shape you into a better human overall. As I said, someone might already have done your idea of a business, product, or even song—that is fine, really. You just need to be able to differentiate the good ideas from the bad ones, and then execute that idea better than its predecessor.
So how do you differentiate an idea? There's one word for that—Research. Research the market based on the product idea. If this is a software that is able to buy flight tickets for cheaper, see who's in the competition. Research what they're great at and what they're bad at. Believe me, every company, product, or service lacks in some things—you need to find what those things are and approach your product from there.
The thing is, you can just steal ideas. Already successful companies have already done that. Look at Instagram and Snapchat; there was a time where Instagram was massively losing users to Snapchat because of certain features that the young generation liked more, such as the photo filters and timed stories. Due to this, Instagram had no choice but to steal the original idea, yet they tweaked it so much that it became original to them.
All you need is to be able to take an already used idea and turn it into the next big thing by making it authentic. Make it so different that it loses the original owner's label. This is all you have to do in order to build a successful service or product. I'm not saying to steal everything from a product—however, steal parts until you're able to increase your overall confidence to perfect your product via your own ideas.
