It waits for no man woman or ant.
Procrastination really is the sleaziest thief there is. The illusion that there is time in the future to accomplish a task you have now is the fastest way to sink into mediocrity and failure.
The only time to start is now. Not tomorrow or next week. Now.
I have learnt that rather late and I regret it throughly. But am smarter now. There are almost ubiquitous tools that can be used to manage time and resources and thus there really is no excuse.
It is almost hilarious how the opportunities available to us are squandered in a jiffy (This is apparently an actual scientific definition of time.)
Do what needs to be done Now. Not soon.
