Experiment with replacing ‘I should’ with:

I could. I can. I choose to. I will. I want to. I feel like.

‘Shoulds’ are rarely helpful.
Use them to become aware of the things you are imposing on yourself.

Sometimes shoulds might help us see something we want to improve on some level, but it is more empowering to language them in a more consciously engaged way.

This small change in language can help generate and change our relationship with ourself and our level of motivation and energy for things.
