“If I knew then what I know now, I would have been very successful.” A tired expression (a.k.a. cliché)!
I have lost count of how many times over the years I have heard the above cliché as it pertains to business. Even to relationships! Think about it. What you know today can be attributed to all the cumulative learning (a.k.a. experience) achieved on your adventure. Unless you have a time machine, you cannot turn back the clock and take all your current learning (a.k.a. experience) and apply it to the past. A more realistic approach to life is best summated by Danish philosopher, theologian and social critic Søren Kierkegaard:
“Life can only be understood backwards, but it must be lived forwards.”
