Putting things off until later is just plain stupid, regardless of whether you say, “I’ll do it next time” or “I’ll do it tomorrow.” If you feel motivated, you have to act on it right away. Saying, “I’m busy today, so I’ll start later.” is just an excuse that turns into a week, a month, or even a year of procrastination, and you never actually get started. It’s no different than students who can’t bring themselves to sit at their desks and who never make it into their dream school.
とすると、「今度やろうはバカヤロウ、明日やろうもバカヤロウ。思い立ったら何でもすぐやらなきゃダメだ!『今日は予定があって忙しいから〜』と今日寝るまでに始めない人は1週間、1ヶ月間、1年間と[先延ばし](https://eikaiwa.dmm.com/uknow/questions/75411/)にして、結局いつまでたっても始められないぞ。なかなか勉強机に座れない受験生は希望校に合格できないのと同じだ!」となります。
参考になれば幸いです。
