Most of the time the activity doesn’t actually take much time. The older I get, the faster time seems to pass and I have awareness of this fast-time-passing. So instead of avoiding the thing for hours, I just do it instead and am actually fully done with the activity in usually less than an hour. After that you can pat yourself on the back saying that you’re an adult and you took care of an adult responsibility, but truly you are self-aware enough to know you were one tiny breath away from skipping it to do something time-wasting or irresponsible instead. For one more day you get to live the illusion you’re and adult and you can take care of your adult responsibilities.

If you do this more often than not, you actually are an adult and actually do take care of your adult responsibilities on regular basis.
