Training

Waiting for trainee requires quite a bit of patience
tend to forget how one-third of life had been in training mode
if assuming to live to 90
The days of life to be enjoyable in prime are truly countable
Some people need further training to go back to themselves
forgetting dedication to work
forgetting the grinding
forgetting the fame
Some other would do life long training on any hobby
so shouldn't have much impatience other than to their own expectations
