Ask anyone you admire: Their lucky breaks happened on a detour from their main goal. So embrace detours. Life is not a straight line for anyone.
The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.
