’tis the season of hope, so I hope this helps encourage you: There are a kazillion ways to make money with what you know how to do.
You just have to keep trying.
Keep knocking on doors. Walk though every one that opens, even if you have doubts, because you will have doubts.
Don’t let failures get you down. I know that’s hard, but if you’d stopped trying to walk every time you fell when you were a toddler, you’d never have left your nursery.
Find a relentlessly positive friend who knows how to listen, and who will help pick you up when you get knocked down.
You can do this.
