Ambition is exhausting

There is so much I want out of life, so many goals I want to accomplish, but we all know it's hard to keep moving forward steadily when we have to live day to day responsibilities while trying to accomplish them. Sometimes I feel like there's not enough time in the day to do it all. After working two jobs, exercising, running errands, volunteering,etc., I'm wiped out. But I have to keep telling myself that I can't be the person who lives so much in the present that I don't work for a future. I want to write so many more books, I want to launch my youth program, get my doctorate, get married, have one more baby, and just be happy. (So there, I'm putting it out there in the universe.)
With me trying to do so much, I get run down, tired, and frustrated every now and then. I lose focus and have to remind myself that slow and steady wins the race and that as long as I am moving, I shouldn't stress about the pace at which I am doing so. But being the go-getter I am, it gets exhausting. Then I have to wind down, rest my mind and body, recharge, and attack life again. Do you feel me?
