why change ways when stress is required for that change?
In the end, will anything that came before that end matter in the end?
To leave a legacy. Something positive to be remembered by is the best answer I can think of.
Whether that matters or not is up to you. You can choose for it to matter or you can choose for it not to matter to you at this time. You can also change your mind over whether it matters or not at any time before the end. The sooner you choose for it to matter, the more time you will have to carry out the change you already know you wish to make.
The question may arise, can you handle the stress? Yes of course you can, you've handled stress before.
That's the best answer I can give speaking in a general sense. For a more detailed analysis I would of course require more specific details on what exactly you are talking about.
