I find if I write down 5 tasks and cross them off one by one, I will gravitate to the short easy ones first for instant gratification.
Completing larger tasks gives a much deeper satisfaction yet despite a long time trying to teach my body/brain this, it still craves the easy path instant gratification.
So one thing I do is split up the big task into lots of small tasks so I can cross more off and get the gratification hits. This helps my brain prioritise those over other small tasks.
Some people advise 'eat that frog' aka force yourself every morning to start with the most unpleasant (and you know which one that is...) task first, and the rest of the day is a breeze.
One thing that I've realized is that sometimes starting on those little easy tasks and crossing them off builds momentum for the day and then you can tackle the long/unpleasant ones. It's like doing a warmup set, it will get you in your workplace and started on doing things.
