Know how to give constructive(helpful) feedback.

While giving feedback to friends or someone else works, post or comment on social network; it's always a great idea to think before you write and post any feedback. Also, usually constructive feedback are feedback that tell the writter exactly what is right or wrong about their work. It just not simply like "good", "I like it", or "It should be better". You have to tell exactly what do you mean, and how to improve it or keep on making progress with it. Your feedback don't need to be extremely, and it should not be. Just keep it simple, tell if you like it or not, then explain briefly why. Don't use bad language in the feedback, comment is a way to help people improve, not to show them that you hate them. There is a lot of way to create a constructive feedback, but the main point is don't use inapropriat language, and try your best to explain what you mean.
