Find things that will grab your attention. For example; I pick up a travel magazine when I go grocery shopping. Therefore, later in the day something will come to you creatively not only from the topics you have read but, the flow of ideas will come. Its a great tool to expand your creativity.
Looking at things and circumstances with and open mind, ideas come when your seeking the future or retrospecting on the past. Just pay attention to the clues.
Try to remove negative attitude. Negative thinking will block creative brain motions and, cause confusion. Everyone has an argument but when it ends the thinking of "I could have said this or that". There are no bright ideas that can spring from negative thinking.
Set up your own universe for creativity, the environment will make ideas become easy access. For example; pull out for favorite album. Get in tune with the song, feel the rhythm, sing along. However, if you loose focus reflect upon the positivity of the creative atmosphere.
The best way to inspire yourself is to be around creative people. Someone who is always creative something or giving you new ideas. Keep them around you study the way they think, soon you will mentor others on creatvity.
