Barriers faced

FactorsStatement
Educational EconomicLimited schooling. He was one of seventeen children of a Boston candle and soap maker. He started grammar school at 8, and at 10 his father took him out to work in the family shop.
Economic SocialA harsh apprenticeship. At 12 he signed indentures binding him to his brother James, a printer, until age 21. James often beat him, and Franklin eventually ran away to Philadelphia.
Economic SocialA broken promise. Pennsylvania's governor, William Keith, encouraged him to go to London to buy printing equipment, but the promised support never came. Franklin worked in London printing houses for about eighteen months before returning.

What helped

FactorsStatement
Educational EconomicBooks through his trade. His father chose printing for him because of his love of reading, which gave him daily access to printed material.
Social EducationalA network of peers. He formed the Junto, a discussion club of tradesmen of moderate means seeking self-improvement.
EconomicTime to think. He retired from his printing business in 1748, which gave him leisure for science.
SocialA door-opener in London. Peter Collinson, a Fellow of the Royal Society, gave the Library Company a glass tube for electrical experiments. Franklin reported his results in letters to Collinson, who arranged their publication in London in 1751 as Experiments and Observations on Electricity.
Social SocietalRecognition. The Royal Society at first judged his letters not worth printing in its Transactions. After a French experimenter confirmed in May 1752 that lightning is electrical, the Society awarded him the Copley Medal in 1753, its highest scientific honor, and Harvard and Yale gave him honorary degrees the same year.

Notes
