Always preferable not to walk across rushing river before coming to bridge. Most imagined calamities or fortunes of tomorrow never make it to today. No need for worry, stress over things that may not occur. Man who dines on dreams of tomorrow’s dinner soon die of starvation. Also no need to revisit turbulent past again and again. Most esteemed gambler once say wise to bet on horse in race today - cannot win money today on horse running yesterday.
