I was once in the same situation. I sat down outside and had a cup of coffee. I watched the autumn leaves fall, the clouds roll by, heard the birds chirp and the wind breeze past my ears, thinking about what I should do. I thought of nothing.
After a few days of doing the same thing, over and over again, I finally decided on what I can do. I sought to learn, to experience and to see all that I have yet to know. Until now, I've been cooking, learning every week what I should or should not do in the kitchen. I've decided that I'll go skydiving with someone sometime soon. From that point on, I've decided to explore a bit more; from that point on, I've been ordering food that I haven't tasted or known in restaurants and such. A few days ago, I had the chance to order a milkshake of sorts, two flavors of ice cream blended together. I chose mint chocolate and passionfruit. It was a very strange, yet pleasant experience.
Just as >>3
had said, take a moment to find other goals.
There's an entire world out there that needs to be explored. If you have the money, travel around the world. Go sailing with a friend for a few days out at sea, try a new sport or a martial art. Try hiking, camping out in the woods, hell, try a different job. Save someone's life, donate some blood, do volunteer work, clean your neighbor's yard, do some gardening, plant your own vegetables.
Just don't be afraid, anon. There'll be at least one thing that you might like, and it may even change your life. Have a great week, and don't forget to smile.
