Im 30 and I only have 1 year of experience... Will I ever have a decent career?

My entire life I have spent it being a loser, messing up, getting fired from jobs. I have a degree, but it took me almost 10 years to finish! =[ Im really embarassed to give people my resume, people who want to help me out. Im even ashamed to put my profile up on linked in because Im afraid people will know i've been a slacker my entire life. Is there any hope for me to have a good career, to ever have a position of leadership, to do what i love??
