I have personal goals in life I want to reach and I’m going to do whatever it takes to do so. Try laying out your life goals… What do I want to do 5, 10, 20 years in the future?
As a relatively young person but older than OP myself, this is exactly what I did to get out of the slump of knowing how the system is stacked against us all. I set myself goals, and kept updating my goals. I had a 6 month, 1 year and 3 year plan at any point. Longer than 3 years it’s hard to set specific goals because too much can change in that time frame. I always had goals to work towards and make myself a better version of me. If you can continually be a better version of yourself than you were before then you’ve won the game of life
You know what’s better than the bare minimum? Give your work more than they expect, but keep some of your potential to yourself. Only give work 70% and keep that other 30% of yourself for yourself. You get all of the benefits of being an overachiever with none of the drawbacks.
You know your job is as safe as it can be because you’re exceeding expectations, and you can reap the bonuses and pride that brings but you still have remaining capacity to do more in your personal time. Plus if you’re not completely applying yourself every day you can hit the grindstone on a really bad day when SHTF and really come out looking like a hero
