Most solutions create new, unforeseen problems - this is the law of unintended consequences.

Try not to merely think about things, but to think through them - all the way through to what their likely effects would be. It's physically more tiring doing this type of thinking, because you're having to generate all the possibilities and the mental images to match, but it's going to save you a lot of time in the long run.

Don't just look at what could go right for you, however nice it is to do that. Dare also to look for the traps, ask the awkward questions, probe the areas where things could go wrong, or are already going wrong.

Try to think of the unexpected, then test your ideas out as cheaply and quickly as possible. The best minds are unstoppable experimenters.

You should implement your problem-solving solution and then keep an eye on things to see how well the solution is working. Prepare to modify it or scrap it altogether if needs be.

Ideas are ten-a-penny until you have to put them into action for yourself. So you've thought of something? But can you do it or get it done? Ideas should be live ammunition.
