I am a huge procrastinator, so I have to do some elaborate stuff to get myself to do things. Anxiety producing methods don't work very well because I just feel overwhelmed and that doesn't help things. The best technique I've found that consistently works is to write down the things I have to do today in my phone and to close my eyes and visualize getting them done repeatedly. I imagine myself doing the actions one after another that I need to do to complete the task. I do it multiple times in a loop until I lose my fear of it. I write down the steps if it's long and I can't keep it in my short term memory and go through that.
