There is No Hack, Sitdown and Get it Done

Lately I am behind with my work due to the full day training that I attended. I feel overwhelmed when I look at my task list. I still try to have a regular day which consists of regular breaks and walks. After attempting for half a day to clear my task list, I know it is impossible as my other regular work starts to pile up as well. The only way to clear my list is to sit my ass down and start going through the list. I batch all my calls and emails into one session. There is no hack or fast track strategy. The whole session was just me and my to-do list. I know and have many tricks to stay productive. The most effective way is still brute force; start and get it done.
