What is ‘ideal?’

The ideal timeline? Maybe the ideal budget? Or the ideal client? When you have all of those, or maybe just two, then is it ideal? Maybe?

The need for circumstances to be ideal is a great goal. But it’s also very unrealistic.

Should it all be in place for a project to get off to a good start and is getting off to a good start a necessary precursor to a successful project?

The answer to both is NO.
