Multi-million dollar business or not, quick and easy, is not how to run any business. Preparation is the big word and it begins with education, whether formal or informal.
Thomas Edison became an avid reader after his mother tutored him from home. He had only three months of formal education and by the time he died he had patented over one thousand inventions.
Henry Ford completed his first gasoline powered car in 1896, the quadricycle. He also invented the Model-T (1908) and the ever popular V-8 engine (1932). His formal education was practically nil, but he did receive training as a machinist at age 15.
In regards to formal education, societal challenges were somewhat different then from now. Many young men were either forced to farm the land or leave home at an early age, but then there were those men, such as Edison and Ford, that had within them a burning desire to create, regardless of the formal or informal education that they did, or did not, receive.
Some would define education as attending school grades one through twelve and making the mark, but education goes much further. It's more than three plus four equals seven. It's learning creativity, satisfying curiosity, acquiring reliable knowledge, and responsibility in time of deadlines, social interaction, dependability, and awareness.
The bottom line is, if you like what you do, you will do well, because if you like what you do, you will become educated somehow, in some way, shape or form, because you are driven.
A motivation that seeks progress is learning and learning, whether big or small, formal or informal is education.
