I am a pure Gemini, so we get bored by doing just one thing, so I like to work on few projects at once. You will say that in our culture multitasking is a skill to have. But, I would say that if you don’t have a real system of work so you will be able to work on one thing at a time, you will fail like crazy.
The stats say that more than 90% of entrepreneurs have more than one business. You would say, the more, the better, because it is very cool to be a serial entrepreneur. In most cases, it is a very bad idea to proceed this way.
