I suggest you to make use of “Adobe Illustrator” as it is far better than Photoshop for logo designing. But the main thing which will inspire you to start doing best logo design is your own interest and enthusiasm. Just free your imaginations and start finding ‘pictures’ in various words. Try to observe shapes in the letters and then implement your thoughts in reality. If you want to be more perfect in doing this, you can go for various tutorials or courses on internet.
