Accept that no matter where you go to work, you are not an employee you are a business with one employee, you. Nobody owes you a career. You own it, as a sole proprietor.
The sad news is, nobody owes you a career. Your career is literally your business. You own it as a sole proprietor. You have one employee: yourself. You need to accept ownership of your career, your skills and the timing of your moves.
You have to pretend you're 100 percent sure. You have to take action; you can't hesitate or hedge your bets. Anything less will condemn your efforts to failure.
