agree with the above. Haikus are generally considered to be an 'easy' form but actually they are tricky simply because they are short. In a short poem like a haiku, you have to make sure that every word, every syllable is absolutely essential. If they aren't, then you're in trouble. As far as haikus go, this isn't particularly strong but it's not bad.
Also, the repetition of the word thought is not good. But that's already been mentioned.
