A lot of people think the answer to these simple questions will tell you everything you need to know; I agree, but I also believe a lot of people confuse needs and wants. People who chase after wants often chase what they need away.
If you chase after things you don’t need, the sacrifice will not be justified. The only change you really need to make in life is your attitude to the life you already have.
