Sincero, Jen

Sincero is a master of her craft in helping people effect permanent changes. Her book is highly recommended.

"Badasses" will be inspired by this feisty, unconventional guide to crafting a prosperous life (and bank account).

Self-help novices and general audiences happy with a more material view of success will find Sincero's colloquial approach refreshing and celebrate her frankness. However, those looking for a more holistic and sophisticated view of success may prefer more researched works like Brendan Bruchard's The Charge.
