The feeling you get after you finish a task is priceless. I can’t explain it, but you know it. When you were going to school or college you used to get that feeling after you completed your exams.
But, you can’t be in relief mode for a long time. This will lead to procrastination. There is a poem by Robert Frost “Stopping by Woods on a Snowy Evening”, which I would like to quote here:
The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.
