Getting Rid Of Tenacious Thoughts

I realize that one of my major beliefs is: “life is a lot of work.” I make it mean that it’s impossible to get something without working hard. In some way, it is true because we all need to take certain actions to get a result. However, this belief also tends to discourage me and then prevent me from acting.

Translated into a model:

C: Life
T: I will never get anything without a lot of work
F: discouraged
A: I might sometimes renounce to take actions because I’m tired of always “working hard”
R: I will indeed not get the results I wanted

How can I adjust this belief, knowing that life gives everyday evidence that I won’t move forward without “working hard?”

Thank you for your help!
