It depends on your perspective.
What price would you put on learning how to start a business with your skills? Or to finally find your gift and earn a living from it? What is it costing you to not follow your passions because of continuing in a job you don't even like?
Be honest; do you think you can get all these benefits at a better price?
Staying where you are is difficult, but not going for the life that you deserve is even worse.
Think of it like this - investing in yourself is the only 100% secure investment.
