Lindsay Lohan is determined to ''love'' herself ''no matter what''.

The 29-year-old actress has embraced a new positive mental attitude and insists she is going to ignore criticism and shut out the haters in order to be the happiest person she can be.

Lindsay - who has overcome various legal problems and substance abuse issues in her short adult life - has taken to Instagram to inform her followers of her fresh mindset with a post which appears to be aimed at critics of her slender figure.

Accompanied by a risqué photo of her in a red and black corset and white bodysuit, she wrote: ''I love my waist just the way it is. Love yourself and be kind and you shall succeed no matter what. Be Strong inside (in everyday/ man or woman lol) (sic).''

Lindsay's new attitude and travels around Europe this summer seem to be the inspiration behind her next project, an ''educational'' book on style and fashion.

The 'Mean Girls' actress has reportedly turned down several publishers' bids for a tell-all autobiography, and is instead turning her hand to a different type of tome.

A source recently said: ''Lindsay has had numerous offers to do a tell-all book about her time in rehab, her brushes with the law, her crazy family, or to lift the lid on the less glamorous side of a Hollywood starlet. But she refused those offers, and she's working on something related to style and fashion and her travels, an educational book.''
