It is simple.
Stop worry about LR. It eventually will happen.
When you work at Cisco, save most of your money. Live cheap.
Once LR'd, if you can say last at least 15 years, you will have enough to not have to get another series of high-paying, time consuming, and stressful jobs.
Post-LR, I make a third of what I made at Cisco now three year out (by choice).
Stop letting the money control you.
