QUESTION: - Is it true that life tends to be symmetrical?

Yes, and here is the scientific(?) proof showing how one's view of success is perfectly symmetrical: -

• At age 4 success is . . . not piddling in your pants.
• At age 12 success is . . . having friends.
• At age 17 success is . . . having a drivers license.
• At age 35 success is . . . having money.
• At age 50 success is . . . having money.
• At age 70 success is . . . having a drivers license.
• At age 75 success is . . . having friends.
• At age 80 success is . . . not piddling in your pants.

So even if you're aged 4 or 80 you're quite likely to have something in common . . . unless your successful!
