In the upcoming time, you are being advised to look into the concept of 'opportunity cost'. Move from the mindset of deprivation to prioritization; instead of looking at what you are losing, look at what you are gaining through this opportunity.
How you trade your time for income, should not be about about surviving on the time and energy that is still left, but can better be seen as a deliberate payment to yourself. Do not spend your hard-earned money on 'lifestyle inflation' to soothe the stress of a high-paying job.
Allow your career choices to be a conscious trade-off rather than a sacrifice. Don't see a job as a loss of time and peace that is forced upon you, but as time and future freedom you are gaining. Also think about this: are you learning a skill or are you just doing a task, because perhaps there is an opportunity to be found here...
Confidence comes from understanding which alternative you consciously said no to, so you can say yes to a higher priority - and thus the regret disappears.
See it like this - Currently you are living like a firefighter, constantly reacting to heat, and running towards the loudest alarm, feeling exhausted by forces outside of your control. But now you can see yourself as a conscious architect.
When you don't buy a (bigger) car like most people do when they have more income, you will eventually have enough income to drive to wherever you want without needing to pull over at a 'job station' ever again.
Don't see a high-paying job as installing artificial grass that looks good but doesn't grow. See it as you planting a fruit tree which will give you shade and food for years to come. You might not see its fruit in terms of income and freedom right away, but over time as the tree will grow on its own you will.
