To do it or not…

I have an idea to do something. But I am not sure if I can to do it and I am not sure if I can manage it myself. I am pretty confident with myself though. But still, I might need some help on the way to achieve what I have in mind. But then, I am not very familiar with some of the stuffs. But all I have is myself. Its gonna be rough. How?
