Often I find myself surfing the internet for want of something to do, or wasting time in other ways. But then I realize that each of us has only so many breaths that we're allotted.
If I want to reach certain goals, then I realize that I need to get going on them, and this motivates me to put my time to good use.
This is especially important with spiritual goals, with which the tendency is to put them off for some future time. But when will that future time come?
Best to work on them in an ongoing way. Don't put them off.
