I think a very simple and effective way to start seeing more positive things in life is to have a journal and every day before going to sleep to think about 3 (or more) good things which have happened that day and write them down! It seems like a super easy thing (but who said only difficult things work? Maybe this is the issue we normally face.. We tend to over-complicate life...) to do but it really works.. I think sometimes we don't appreciate all the good things we have/experience since life is quite hectic.. but we have to take these few moments every day and try to reflect.. it can be anything... maybe someone smiled when gave you a cup of coffee, maybe you saw a rainbow or maybe your favorite song was playing when you entered a shop. We just have to learn to capture these magical moments and we will see that every day there is smth to smile about! :) I don't know you but I am sending you some smiles virtually! :)
