While the meme gives you a great summary, here is some more of the story, as I see it.
While there are external factors that influence our lives, we are substantially responsible for what we think, what we accept into our deliberations and on what we put our attention.
If you know your basic purpose in life and think of ways to align your activities with your basic purpose, producing products that are needed and wanted by others then you are far more likely to have a happy, productive, satisfying and successful life.
This I wish for you!
