Congratulations! You will never look back, believe me. I never got the satisfaction of sending my resignation letter to my last employer, as I was made redundant. I had planned to quit the following year when my side business could support me, but I got the bonus of a nice redundancy payout. You are bound to feel a bit nervous, I know I did when I realized I was the only one responsible for paying the bills, but it gives you a great sense of empowerment in your life.
