To travel hopefully is a better thing than to arrive
Hope and anticipation are often better than reality.
This phrase is a Robert Louis Stevenson quotation, from Virginibus Puerisque, 1881:
"Little do ye know your own blessedness; for to travel hopefully is a better thing than to arrive, and the true success is to labour."
Stevenson was expressing the same idea as the earlier Taoist saying - "The journey is the reward."
