That could mean consciously making the best use of your time outside of 9 to 5 (take vacations, exercise, healthy diet, good sleep, relax after work, enjoy the weekends, etc).
Then slowly and over the longer term improve the situation to your liking strategically (for example by strategically changing jobs).
Taking extreme steps is very unlikely to lead to a good outcome.
You will probably not enjoy being a Ski instructor as much as you may be tempted to think.
For example instead you can aim for getting a remote job then go skiing for 1 month somewhere and ski and work.
In summary try to find a way to peacefully co-exist with a 9 to 5 office job while you progress in your career and strategically and steadily shape it to be more to your liking.
This way you can set things up on the right track so that in 5-10 years you have a well paying and comfortable job that you can quite happily live with.
If you take a more extreme step today like becoming a Ski instructor you may enjoy it in the short term but in the longer term you trade one set of problems for a whole another set and in a few years you may be painfully forced to go back to "step 1".
It is probably better to start somewhere uncomfortable and work towards comfort and balance over time than jumping straight to something dreamy.
Consider that there are probably 35 year old ski instructors who would kill to be electrical engineers with 10 years of experience sitting behind desks in offices, earning good money and taking yearly skiing vacations.
And yes it's all a lot easier said than done.
