Has time travel been invented? No. But do some people act as if they are time traveling? Probably yes. How? I keep seeing people worry about tomorrow. They keep thinking and imagining worrisome situations that may happen tomorrow.

Then they imagine dialogues that people may say tomorrow. Then they start preparing answers for those dialogues. Then they start planning solutions for problems that they think will arise tomorrow. They even start having fake arguments in the shower! They go very deep into their imagined tomorrows. In fact they start living tomorrow, today. Their body is in Sunday but their mind is already into Monday afternoon! These people have started time-traveling. They have thus destroyed the joys of today by worrying about tomorrow. How sad! If only they learnt to relax and let tomorrow’s problems be handled by tomorrow's people!
