Thanks. Although NOT DIRECTLY related to Q 1 let me share this, nevertheless.
Einstein's Theory of Relativity was explained with this example of time. When you wait for your lady love to arrive even 10 minutes seems to be an hour or even longer. But when you spend time with her discussing things, even an hour seems to be less than 10 minutes. Time is the same but our perception of it makes the difference. In Marketing they say it does not matter how good your product really is BUT how people perceive it only matters. Coming back to Time, Paradoxically only a really busy person finds time to all the things that matter - prioritizing things. Time is a scarce resource for him and he tends to use it wisely and optimised its use. (Modi is an obvious example - how he packs so many events in his schedule is a wonder). While a lazy fellow who has all the time in the world never fulfils any thing - procrastination and lethargy. This only goes to prove that ANYTHING we have in EXCESS we tend to waste. This is a general rule and there could be exceptions.
