I'm not sure this is a success, but more of a habit I developed that helped me a lot.<p>While in bed about to sleep, I take about 5min to do the following:<p>- Think about 3 bad things I did during the day<p>- Think about 3 good things I did during the day (from smiling to a cachier, to helping someone in need, to sharing knowledge with co-workers)<p>- Re-visit what I did the whole day and be thankful for everything. And I really mean litterarely for everything (made coffee in the morning? I'm thankful for having a coffee machine, a full fridge, thankful for the weather, money I have or don't have..etc).<p>The above has helped me with two things: Remembering things (I have a bad memory) and be more happy with what I have. And as someone said "Happiness is doing more and expecting less".
