From time to time, like all writers, I can’t help thinking about inspiration and creative potential. Inspiration is like oxygen for me and for millions of people all over the world who make a living in a creative field. Earlier, I believed that creativity was an inborn trait. But now, I’ve changed my point of view and know that every human being can develop creativity. The main thing to do is to be in constant search of inspiration, because our creativity and productivity depend mostly on the mood and other emotional states.              
    It often happens that talented people, who’ve already faced a creativity crisis, become upset and believe that their creative potential is already exhausted. All writers, designers, musicians and painters should know that occasional career ups and downs are absolutely normal.
    Every time my inspiration fades away and I start thinking that it’s all over, I explain to myself that it’s nothing else, but fear. It’s just a fear of losing the talent and being left out in the cold. Some people prefer to wait till everything returns back to normal, while others spend huge sums of money on a journey around the world to catch the wave of inspiration again.
    Without doubt, travelling is extremely beneficial and it broadens the horizons, but unfortunately not everyone can afford such an effective inspiration booster. There’s no need to travel all the time, because inspiration is everywhere. I’ll try to prove that you can nourish the imagination and spirit just by exploring your surroundings.            
    I’m not a psychologist, but I’m greatly interested in solving and thinking over different issues that make the life of humanity more meaningful and complicated. Unlike many people, who by all means, try to avoid dwelling on complex and sometimes even painful issues, I tend to look at the challenge from different angles.     
    Psychologists state that difficulties, conflicts and dilemmas can serve as inspiration for mentally strong and emotionally stable personalities. When we stir up debates and focus on difficulties, we experience some kind of stress. Besides the side effects, this stress and emotional tension activate human imagination and sharpen perception. These psychological processes often give birth to new and unusual ideas and make the mind more productive.
