The recipe of the ancient philosophers
No matter how inventive a person is, there is always that situation when our mind reaches a dead-end problem. Most of the time it looks like there is no exit and we can't generate alternative ideas. In other words, we got stuck into our old and static understanding of a given issue. If you haven't got here you are most probably out of the problem-solving business. Of course, there are many tips and tricks that you could find on the internet and try to apply like watching videos or brainstorming with your colleagues. But sometimes it doesn't work. Well, there is nothing wrong with you. It's natural to find yourself in such a cul-de-sac. It's a problem as old as the human world and the resolution could be something as simple as a little walk by yourself or with some friends of yours.
