What I don't want to be like

good job

1) We all know people who see life only in dull and dark colors. Starting anything new, they go over all possible "what ifs" and focus on a negative outcome. Those people are pessimistic. 2) Have you ever had a feeling of being overworked? And no matter how hard you try, you don't see the end. You are stressed, and exhausted. You have been snowed under with work. 3) Each of us has have those moments of sadness in our life. Sometimes, we have a reason to be sad, sometimes we don't. But every one of us is familiar with that emotion.

Very good. Once again, your English is almost impeccable and your writing skills superb. There were just a few missed commas here and there and one comma you didn't need where you needed "and" instead. Also, it is not inherently wrong, especially these days, as many strict grammar rules that used to exist have continually eroded away in the post technology chat and text culture that constantly rejects proper grammar rules, but it s good to try not to start a sentence with "And". This is what most English grammar text books say to do.
