Push People, for their Happyness

If you your people into doing things, which are useful, but they are not willing to do now, helps them in the long run... After the event is over, they will be more happy.
If you agree to them, and show so called "leniency/mercy", and they don't do that "thing" now, they may well loose the opportunity to demonstrate their capabilities... and be sad after the event.

Example-1: My 3-year son, had to attend sport-day-event in their school... he was not going inside... he stuck to me... he was crying so much... I felt sorry for him, and kept him with me... he didn't participate... the result: he lost the joy that opportunity and joy of being in it... I go so sad, so many children are performing... this guy sitting in lap... I also missed it...
Example-2: The same son, same school... annual-day event... had to perform dance in special dress... as usual he saw somuch crowd... started crying... stuck to me... but, this time, I pushed into the classroom and came out and sit in the audience... the result: he cried in the classroom for some... I could here that... after some time the fruits came... he along with other kids came onto the stage... I was happy... I started my mobile phone video camera... he performed for 1-minute... some parrot-dress (hindi song - tota hoon main tota hoon) ... now he played that video on mobile, some 100 times...
Example-3: My team members, working in other Division project... there was some programming test... they were in dilemma... and fear-factor... already recession period... what happens if we perform badly in test? some of them didn't want to take test... I told them "this is optional for you... but, still it better if you take this test"... strongly recommended... pushed... assured them of no side-effects... they took the test... test was simple... they are happy...
