Not Every Day is a Good Day
Not every day is a good day. We cannot be happy every day. If we are happy every day, we are probably in a mental hospital. It is only through suffering that makes us appreciate the good days.
Whether we are playing games or building something. There will always be setback and frustrations. These are all sufferings. When we manage to have a breakthrough, that's where happiness comes. The greater the suffering, the greater the happiness it generates.
Whatever that you are doing now, please hang on there. Your happiness is waiting for you.
