Be happy. Secondarily, help others achieve happiness. Positive things reliably flow from that.

If you are currently trapped in survival mode and can't help yourself, look for someone else you can help.

As far your questions lead to sustainable happiness, they are worthy of your time.

Past that, those answers follow your experience and circumstances, things that are always in a state of change. Never stop reassessing.

If you're looking for yardsticks: Be kind. Do what it takes to learn empathy. Let other individuals' well-being become important to you.
