Put things into perspective. People who obsess about what others think tend to put ‘issues’ under the microscope and can't see the forest for the trees. People who don't obsess about what other people think tend to look at the big picture. You only get one chance at life; are you going to allow other people’s thoughts to make it less enjoyable? Sounds silly now, doesn’t it.
Give it some time. Apart from the fact that life really is too short to worry about things like this, the other aspect is that people’s feelings change. For example, say one moment people insult you for wearing yellow shoes, giving you the impression you shouldn’t wear them. What if this person's opinion changes, and they start wearing yellow shoes themselves? People change their minds, so what they think now might not matter in the future.
Make a list of all the things that you are grateful for. Putting it into a list really helps. It makes things tangible, more real. Once you see everything that has gone right for you — maybe your family, your intelligence, your health — you begin to realize that life is more about what you do have than what you don't have. Be appreciative of what life gives you, not resentful of what it doesn't.
Take pleasure in the small things in life. Begin to see beauty in everyday things, like a child playing with a dog. Take comfort in everyday things, like a warm cup of tea. Find happiness in everyday things, like a story about overcoming hardship, told by your friend.
