Have you ever tried to do something new, but gave up after trying to do it for few days. Well your not alone dude, many face similar situation. 

Go through below points, maybe it could help you.

1). Start with why

Before you start anything get yourself clear with why.
Only if this question is answered, you will be able to stick with your work for a long time.
Always go to min 7 deep levels of why.

Etc.,

2). If your not sure with why, that's okay
Just start with what you have and figure out later.

3). Never start with mentality of bringing a revolution in the World.

Make sure you have enough in your pocket first, only then you will be able to give it to others.

4). Build your skills, once you figured out your root desire.
Develop 1 hard skill and 2 soft skills

Eg : If you want to create something like boat( headphone)
Hardskill-> building product

Never be afraid to take risks, seek help. Let go egoistic and conservative mindset.

Don't compete, instead collaborate.
