The easiest way.

Don’t do anything.

But it is not the only way. 

There is another better way.

Do something that’s so small and non-risky that it can’t fail.

Or even if it fails, you won’t lose a lot of time and money, working on it.

This way you fail small and your financiers, energy, resources and motiations are not wrecked.

With energy and money buffer you can go after new opportunities and get a chance to succeed.

Failure is not inherently bad, because there is learning in it but it should not be so big that it kills your chance to go after other opportunities or takes a really long time that you never get back.
