Don't tell yourself thet you'll do it later do it now!
“Today or never, that’s my motto.” – Mary Poppins, Marry Poppins Returns
The way that works best for me is to not allow myself to drag it out. If I decide to exercise at 6 then I am changed at 545, turning everything off by 555 and out the door by 6. Letting yourself drag 5 mins will eventually lead to 30 and then it becomes “I can do this tomorrow”. Instead, tell yourself that “I’m just going to change”, “I’m just going to turn on the workout video”, “I’ll just do it for 5 mins” and you’ll be surprised how easy it becomes for you.
