The troubled actress - whose career has floundered amid a series of legal problems and spells in rehab - insists she is putting her bad times behind her and is focused on getting her life back on track.
Responding to a twitter follower who described her as "forever my childhood crush", she posted: "omg! really? that`s so cool hahaha thank you xoxo - sorry for the ups and downs... only going up up up from here!
"i`m a tough cookie! a focused tough cookie! :) (sic)"
Lindsay - who is currently undergoing community service at the Los Angeles County Morgue as part of her punishment for breaching probation - also revealed she has gotten into a regular routine to be prepared for her unpaid work, and has cut down on her use of social networking websites in order to tackle domestic tasks at home.
She tweeted: "i actually watch the news every single morning when i get up for community service, starting at 5am :)
"i`m only on [twitter] for quick moments at a time lol... i`m actually cleaning - was at community service all day (sic)".
Lindsay`s positive attitude comes as she was praised by Los Angeles County Superior Court Judge Stephanie Sautner, who told her she seems to be getting her "life back on track" during a progress hearing yesterday (22.02.12).
The `Mean Girls` star has 14 more days of community service and five counselling sessions to complete before March 29, and then her probation will be over.
