Why I suck at not doing things at the last minute

I had to wait to the last minute to complete a task. There is definitely a better idea than doing such. Perhaps, somehow I will be a able to trick my brain to start and complete a task well while not having to wait to do it at the last minute. I guess is to just do it. The not so simple task can in fact be perform simply-easily. Stop prolonging the task, stop letting something come in between the intention. DO IT.
