Teamwork is a key element in creating a succefull business. I do not believe that one man has all the skills or can overcome all things in a startup. There will always be things you are very good at and things that are not so great to be done by you.

Therefore to higher your chances for succes it would be a good idea to find someone to partner up whit.

If you are a Team you will have someone to talk to and discuss whit. Maybe your idea is not the idea that are the best for the company.

Let me say it this way.

If you are good a computers stay good at that and find someone whos good at marketing and economics. Then I believe you have a better chances for succes.

So do what you are good at and let the rest be done by somebody else.
