To be happy, even selfishly happy, is one of the key objectives. Then being busy is not an excuse for not seeking the happiness.
Perhaps it’s not the busy at work scene, the only reason. In spite of the best efforts to be positive and commanding positive thoughts, some doubts crept in to slow down or be afraid to seek the happiness in those routine.
Yes, no excuses. The time is always there. And I will be there, back in the real world, for all the good times.
