Definitely not to go back, it is absolutely wrong to go back leaving the present with commitments and responsibilities with whom you share and are there with you.
The things left are left and no one will stop waiting for you, time passes away, things change. The world has only one motion since its creation and will never revolve backwards. Life goes ahead you either carry on or make a new change including the present.
Workout with the wisdom and intelligence we got from the creator, don't act out unnatural by saying emotional stories.
There are no chanakyas or mughals ever remaining as rulers of india, they have vanished.
