- One powerful way on how to achieve happiness in life is to think positively. One thought at a time does wonders for a person's morale. Start thinking positively the moment you wake up. Be grateful for having another opportunity to live a meaningful life. Think about how beautiful the weather is today and how fortunate you are to have such a life. Another effective way on how to achieve happiness in life is to cheer someone up or make somebody else happy. Whether it is someone you know or a stranger on the street doesn't matter.
What's important is the feeling you get after making others smile and giving them joy. It could be as simple as treating your cousins to ice cream or giving someone a big help in a project. Happiness is infectious and spreads easily. It works pretty much like the Christmas spirit. Believe me when I say that you're also doing yourself a big favor by spreading happiness.
