If you have had an easy life and have had everything handed to you and seen everything always go your way, you are at a disadvantage. You may have to be diligent in your efforts to overcome the well meaning pampering of your parents and teachers. Your spirit may be soft. Your ability to fully appreciate the small joys and victories of daily life may have been taken from you.
If you have had to work hard and struggle and put up with a few unpleasant things, you may be better prepared to meet the challenges and enjoy the blessings ahead.
For better or worse, for richer or poorer, there are some circumstances about your birth over which you never had a choice. Be grateful for the good and toughen up against the rest. However, should you be lazy, unfocused, dependent, anti-intellectual, selfish or resistant to change, you are choosing to fail. Blame no one but yourself. You will fail.
