Rethink your retirement. For me, "retiring early" was getting to stay home and bring up my kids and take all the holidays we wanted and then choose a new career. And never stressing about the possibility of us both being out of work. And being able to choose to retrain and take up a new career that suited me. This took a small, debt-free house and a starting sum of $30k (and currently needs about $300k with one modest part-time income and 3-4 teenagers).

After that, I am seriously keen to work out the rest of my life and never retire again
