You might not be good at one thing but you will be better at three others. I learned this the very hard way. But you cannot make everyone happy. What you can do, however, is make yourself happy and that is very very important. So be brave, have faith in yourself, figure out what makes you happy and go do it. Get a job, leave a job, dance, sing, fall in love. Carve your own niche but most importantly learn to embrace the randomness.
