Should one adapt him/herself to the environment and situation, or adapt the environment/situation to his/her needs? Which one of those is "the key to a better life"?

Just watched a video about Eastern and Western philosophy on Youtube and one of the commentators wrote that the thing about Eastern philosophy is adapting to hardships of life, instead of changing your surroundings, in order to achieve happiness and peace.

It made me question this. What is the “better” solution? Is there “better solution” in achieving happiness and peace of mind?
What do you people think? Which would you choose, if one is even supposed to make a choice?

Should we change ourselves, or should we change the world to be able to endure the hardships of life and achieve a happy and peaceful life?
