When we are confronted with a problem, we typically look for a solution by thinking about past problems that we have encountered. Because a certain solution worked last time, we are confident that it is the best. This is uncreative thinking.
A creative thinker thinks about the problem from many different angles. This gives them a number of possible solutions to choose from, which helps them find a unique elegant solution.
The next time you are confronted with a problem (even a very tiny one), instead of jumping to the first obvious solution, take a step back and see if you can find several alternatives. At first this is going to be difficult to do, but with practice you will be able to come up with many alternative solutions to your daily problems.
