Lindsay Lohan says she has realised that personal problems were harming her career and the actress now hopes to move forward by putting work first. Lohan – who has endured a string of legal problems and stints in rehab in recent years – had her probation for a 2007 driving under the influence (DUI) conviction come to an end on March 29. The troubled star admits it has taken her some time to figure out that she needed to correctly address the difficulties in order to move forward. “It’s a tremendous weight I feel has been lifted off my shoulders and I feel really grateful and just happy and ready to move forward,” a website has quoted her as saying. Now that the sentence is complete, the ‘Mean Girls’ star is hopeful she can put her career first and stop the spotlight being on her personal life. “I think I became more of a celebrity and I’d like to bring the focus back to what it is I love to do and what I started in this business for, which is acting. I think this being in my past (now) means it is something I can achieve,” the actress said.
