Nothing wrong with working hard and doing your best... striving for excellence. But most people don't know what "enough" looks like... they just want "more." And they keep filling the "empty spaces" inside themselves with "stuff" and then feeling dissatisfied when the stuff doesn't fill them.
Basic investment to secure income in perpetuity is definitely a good plan.
I generally deny offers from banks' financial planners thinking that I could probably teach them a thing or 2 about money. When growing up poor, one usually learns how to stretch a dollar. There are a few popular books on living frugally and I could probably have written them... nothing I didn't already know in any I read.
Most of my life people considered me a cheapskate, yet those same people are still chasing the almighty dollar. I'm chasing quality of life! I worked hard and now its time to work on relationships and enjoy the fruits of my labours.
