Just occasionally, the hard part can be working out which is the correct basic approach (that is, the one that will result in a solution that is fifty times faster than any other approach can produce, or requires fewest resources, or is the only one that will actually work, in extreme cases). But only occasionally, and in such cases the people who try pointing out numerous starting points to you are very unlikely to suggest the correct solution, because they probably haven't understood the problem - or why it matters what starting point you use....
