Through resourcefulness and hard work, my parents rose from near poverty to being fairly well off. At a very early age, I was taught by my father to know the value of a dollar. I was given an allowance of several dollars a week, and if I ran short, it was my own fault. I worked my way through college, and had to make my money last. Even today, I am a good money manager even though economic times are at an all-time low. There's a passage in the Bible that states: ';Raise a child in the way he should go and when he is old, he will not depart from it.'; No truer words have ever been spoken.
My best friends Grandmother always told us to ';Kill 'em with kindness!'; I really believe that is the way to treat others. This coincides with many spiritual beliefs about giving unto others. I think goodness prevails in most circumstances and have had pretty good luck with it.
Some of the most difficult lessons (experiences) in life are the ones we learn the most from. I don't remember who told me, however it has stayed with me for a long time.
';You can only control yourself'; - kind of goes without saying and although I knew this already it helps to be reminded of this whenever someone else does something that makes no sense to you at all.
Act in a way you want to be treated. If evreyone did that the world would be a better place. My mom said that to me.
There will always be someone who has it better off compared to you and someone that has it worse.
Get up you son of a *****, cause Mickey loves ya!
