Just start. You will learn so many lessons just by doing.

[If] man creates the problem, surely man can solve it.

And if after all this you eventually fail; don't take it personal. Don't be ashamed to start all over again.

It can be a challenge not to let failure, or negativity from others, prevent you from going after what you believe in and what in your gut you know can work. However it is important to face these challenges head on and give them a go and importantly don't beat yourself up if you fail - just pick yourself up, learn as much as you can from the experience and get on with the next challenge.

I've never sued anybody, though there have been one or two occasions I've wanted to strangle one or two people.
