I guess you dont need to set your goals to inspire you to save money. With the good dicipline on saving you can earn a lot and with that amount of
money you can do many things. By setting your higher goal that will make you like dreaming a lot so its like hoping to get miracle to get it without doing
things so that is not a great idea. May be you can set your plan first how to save and how much are you going to save each week or month may be
Sure, but there's again another side of this. In my opinion, working hard and a lot to get as much money as possible (to probably save as much money as possible to fulfill a dream) is also a no-go.
I really like to find a good combination of spare time and time I need to work; I don't want to work 60 hours a week just to earn a lot of money. Working 30 hours per week (for example) might make me even more happy. I think you should work just enough to pay your monthly costs (- don't live too wealthy) and then a bit more to save some money (for unexpected expenses etc).
