This is because majority of our lives we should be striving to be doing what we want to do instead of what we have to do.

That's a great goal. I guess, the best way to achieve this is to become really good (aka productive and efficient) in what you have to do. This will give you more time for everything you seek to do.

For instance: How much time do you spend in the bathroom in the morning? How fast are you in cleaning your home? What's your frequency of going to the supermarket? When are the most people in the supermarket? Are there faster ways for you to commute?

Just alone these 5 questions contain half an hour or more per week that you could save. That's a whole day per year that you could win without losing any quality of life.
