Two tips that are essential to live a happy life. The first one is to be grateful. I cant emphasize enough how important it is. No matter how many pleasant things you do, if you dont learn to be grateful you will always see things negatively.
The second one is to slow down. Life has a lot of simple things you can enjoy. But if you move too fast you will overlook most of them. So dont be in a hurry. Dont move too quick. Slow down and pay attention to the world around you. Most of the ways Im about to share will work well only if you slow down.
