Turn your problems into challenges
Have you noticed that successful people rarely use the word problem? Instead, they prefer to use challenge as they know that the only way to learn anything valuable in life is from trial and error, and that learning from your failures breeds success.
A worthy example of this thinking is Thomas Edison. It took him around 10,000 attempts before he finally invented the electric light. Instead of giving up at any point, he believed that each failure was bringing him closer to success.
So by turning your problems into challenges you can think around them; keep tackling them in a slightly different way; and if something doesn’t work out, ask yourself how you can learn from it in order to help you next time.
It may not always be easy to do at the time but you will be amazed at how it changes your perception.
