Give meaningful compliments. When it comes to giving compliments, the most important thing is to keep them sincere and drop them at the right moments. If you're not genuine, don't compliment. If you're a beginner in complimenting, watch others for timing of compliments and follow suit. You can compliment a person's jewellery, sweater, or new haircut, and move on to give deeper compliments as you get to know the person better.
