I'm clueless.

Which path should I go? I felt clueless of my future. My life is like living each day, count each day. Should I wait for somebody to help me decide which way should I go? All these years have been going merry-go-round, doing one job and hopping to another. I don't wish to carry on this way. It won't make things turn up better. And I'm afraid that I can't find a permanent job. My parents are in their 50s. How many years should I go wasted? I can't waste my time anymore! Not to mention that I want to pursure the psychology course for interest. The first things is finding the right job to work for years. I always wanted to do admin job but everyone told me that maybe I'm not suitable for it. I have been trying my luck to find a simple part time office job on the job positing website Gum Tree that not involve a lot of tasks. But can't seen to have a luck to work in admin field. My mum friend even told me that I can't find a office job that like last time I had worked. And it's true of what she said.....I have went though a lot of jobs online to find a admin job but can't seen to find one suitable. Maybe I should not think of pursuring Office Skills course but this is the career that I really want to pursure. So in the meantime I'm doing some self-improvement and looking for part time packer job position. Is that the right choice? Can your tell me?
