I'm trying to do two jobs as a freelancer, but I can't manage my time, so I put off the work compared to the usual time, but as I finished it all at once at the last deadline, my stamina is gradually decreasing.It's been almost a decade, and in the meantime, the time management self-development book schedule, which is really good, I haven't been able to maintain it for more than a month, so I bought it on impulse. ㅠㅠㅎ
