The same thing is for startups and ideas. If you have an idea right away after it appears in your mind you should go and make a first step to implement it. If you will think too much it will sink in the swamp of never implemented plans and ideas or will just go away or will be implemented by someone else.

5 months of doing everything to achieve nothing.

I had an idea named Great Work. It was a service aimed to help people find their passion. Yes I know it sound crazy and super naïve but I worked on that. I started to work on planning, graphics, presentations, pictures, descriptions, articles, investments and so on. I worked on everything but not the project itself

I realized really simple thing recently. Try is million times better than think. The real world is much more representative than any models either they are built in mind or on the shit of paper.
