Sports—what sports? Team sports give you teamwork skills. School—you may have coasted through it, but it shows you have the organizing and planning ability to manage a project. Social events = people skills. Did you organize the parties? Organization skills? Did you have to resolve tension between party attendees? Negotiation skills.
I’m serious. This isn’t bullshit. You really do have these skills. All you have to do is think about how they prepare you for work. Hell, lack of experience = willingness to learn. Coasting through school = quick learner.
As @YARNLADY said, you can think negatively about your skills if you like, but that won’t really help. If you want a job, you have to think of yourself as a product and sell it. It’s not really you in the job interview. Your self-esteem or whatever issues have nothing to do with it. It’s a sales job.
Also, are you networking? Get informational interviews (you’re not asking for a job, just about work, and at the same time you are selling yourself). Sometimes informational interviews lead to companies making a position for you. In any case, get at least two other names of people to talk to at every informational interview. Get out there. Let people know who you are and that you are looking.
Talk to neighbors, friends, parents, teachers—ask everyone if they know of something—preferably something coming up. Develop an “elevator” talk about who you are and what you want in a job. Be able to pitch yourself in a minute or less. Act confident. You don’t have to be confident, but just pretend that you are a product everyone wants. Just pretend. It’s just an interview. You’re supposed to. Every negative becomes a positive. If you have a negative attitude; it becomes a critical eye and an impulse towards perfectionism (but you are learning to do good enough, so you can get things done in time, even if not perfect).
It’s just a game. Work it. Work will turn up. Finding a job is a full time job. Do it at least 20 hours per week. Pay yourself for it (so you do it—the pay can be metaphorical).
If you think racism is an issue, then turn that around. You’ve learned how to succeed (at school) in the face of dislike. You know how to turn people around and get them to appreciate your skills, and to see beyond the color of your skin.
Get it?
